Why are protein so fragile

Answers

Levels of selective constraint vary among proteins. Although strong constraint on a protein is often attributed to its functional importance, evolutionary rate may also be limited if a protein is fragile, such that a large proportion of amino acid replacements reduce its fitness. To determine the relative contributions of essentiality and fragility to selective constraint, we compared relationships of selection against nonsense mutations (snon) and selection against missense mutations (smis) to protein sequence conservation (Ka).

How is water traveling underground to lost Lake?

Answers

Answer: Water becomes the part of the aquifer.

Explanation:

Water from rain, snow fall, river, lakes, ponds, ocean, irrigation field, and from other sources become the part of the ground water or aquifer. The water seep into the soil or rocks and deposited as reservoir of water underground. The underground water when exposed to the surface can become the part of the lost lake or any other water body. Thus the source of lost lake can be determined this way by tracking the distance covered by the ground water.

Defense as in antibodies.

Transportation and are embedded in the cell membrane to allow substances to move across the cell membrane.

Enzymes that lower the activation energy of a reaction.

Contraction to allow muscle and cell contraction/movement.

Explanation:

Proteins serve many functions in living organisms.

Structure: The most abundant protein in mammals is collagen and is found throughout the body. In a major component of connective tissue such as skin, ligaments, and tendons providing strength and elasticity to these tissues. It is found also mineralized in bones and teeth.

Proteins function as hormones which are chemical messengers that mediate many cellular responses in the body. For example, the hormone insulin is a protein.

Proteins functions in the body's immune system as antibodies which recognize and initiate immune responses against diseases. The immunoglobulin such as immunoglobulin A and G are proteins.

Proteins serves as transporters to move substances across the cell memebrane. Some are found as peripheral or integral membrane proteins. Examples of transport proteins are the glucose transporters, Glut-1, Glut-2 and Glut-4 transporters.

Enzymes are proteins which catalyse the chemical reactions tanking place in an organisms. Various enzymes in the body include the hydrolases, the ligands, the leases, etc.

Contraction of the actin filaments of the muscle which are proteins, allow muscle and cell contraction bringing about movement.

A Note on the other options.

Eicosanoids are lipid molecules which serve various functions such as in regulation of blood pressure or inflammation.

Steroids such as cholesterol are lipid-derived molecules.

Glycogen for energy storage in muscles is a storage form of glucose, a carbohydrate.

In a lever, 120 N load is attached at a distance of 20 cm from the fulcrum. If this effort is used to lift 50 kg weight then, the load distance is:!?​

Answers

Answer:

The load distance is 4.9 cm

Explanation:

Given;

Effort applied to the lever, E = 120 N

Load overcame by the effort, L = 50 kg = 50 x 9.8 = 490 N

distance of the effort from the fulcrum, e = 20 cm

let the distance of the load from the fulcrum = d

The following simple set-up is used to illustrate this lever;

  -----------------------------Δ-------------------------------

 ↓          20cm                             d                   ↓

120 N                                                                490 N

Lever operates on the principle of moment, so take moment about the pivot (fulcrum);

490(d) = 120(20)

d = (120 x 20) / (490)

d = 4.9 cm

Therefore, the load distance is 4.9 cm

The selective serotonin uptake inhibitors, like the antidepressants Prozac, Zoloft, or Paxil, result in increased levels of serotonin at synapses, which may _____ initially but then lead to _____.

Answers

Answer:

increase anxiety; decreased vulnerability to overreact to stress

Explanation:

Serotonin (5-HT) is a natural neurotransmitter that carries signals between nerve cells (neurons) throughout the body. This neurotransmitter (serotonin) is responsible for regulating many biological functions (e.g., mood, digestion, sleep, etc). Moreover, it has been shown that there is an association between low cerebrospinal fluid 5-hydroxyindole-acetic acid (5-HIAA, the principal serotonin metabolite in the brain) levels and the risk of developing depression or destructive behaviors. In addition, serotonin concentration can also be elevated in situations of anxiety and/or stress. Antidepressants such as Prozac, Zoloft and Paxil act as serotonin uptake inhibitors that increase serotonin concentration at the synaptic site. Like other drugs, these antidepressants may lead to increase anxiety and decrease the vulnerability to react to stress by downregulating sensitivity to serotonin released during natural stress situations.

2. Nucleus a) The dense, active protoplasm found in the center of the cell

3. Cytoplasm b) The watery fluid that surrounds the nucleus of the cell and is needed for growth, reproduction, and self-repair

4. Cell membrane d) The part of the cell that encloses the protoplasm and permits soluble substances to enter and leave the cell

Explanation:

Mitosis is the process that undergoes a cell to give two new identical cells. This is how our body makes or renovates tissues.The nucleus is the part of the cell that contains the DNA, which is necessary to synthesize the proteins that the cell and our body need. It is in the center of the cell and has a nuclear membrane that separates it from the rest of the organelles.The cytoplasm is a solution that surrounds the nucleus, and it contains the rest of the organelles that the cell needs for its functions. The cell membrane is the structure that encloses all the cytoplasm and the nucleus. It is made of phospholipids, proteins, and cholesterol, which allows the passage of certain substances.

Facilitated diffusion requires
A. a protein pump, energy, and a concentration gradient.

B. no energy, net osmotic movement, and a protein pump.

C. a concentration gradient, a protein channel, and no energy.

Answers

Answer:

A.

Explanation:

TutorialDiffusionDiffusion means that the net movement of particles (molecules) is from an area of high concentration to low concentration.

Graph of the simple and facilitated diffusion taking into account the rate of uptake and the concentration

If the particles can move through the lipid bilayer by simple diffusion, then there is no limit to the number that can fit through the membrane. The rate of diffusion increases linearly as we add more particles to one side of the membrane.

If the particles can only pass through protein channels, then the rate of diffusion is determined by the number of channels as well as the number of particles.

Once the channels operate at their maximal rate, a further increase in particle numbers no longer increases the apparent rate of diffusion. At this limited rate we describe the protein channel as being saturated.

The cartoon illustrates several points about facilitated diffusion. The particles are more concentrated on one side of the membrane, and yet they can move in both directions. However, the net movement is from high particle concentration to low. If the number of particles gets so high on one side of the membrane that they interfere with diffusion through the protein channel, then we observe a limit to the rate of diffusion at the point of saturation.

Facilitated diffusion requires a concentration gradient, a protein channel, and no energy.

3.
If a hawk eats 30% of the weasel population, weasels eat 30% of the mouse population, and
mice eat 20% of the wheat plants, calculate the total numbers of each organism that exist in
this ecosystem
a. Start by finding how many weasels there are to support the one hawk
i. # of weasels eaten 7.3 = total weasels
ii. total weasels x # of mice needed / .3 = total mice
iii. total mice x # of wheat plants needed / .2 = total wheat plants

Answers

Answer:

a. Approximately 1,003 weasels, 3,345 mice and 16,729 wheat plants per one hawk are in the ecosystem

Explanation:

The percentage of the weasel population eaten by a hawk = 30%

The percentage of the mouse population eaten by a weasel = 30%

The percentage of the wheat plants population eaten by a mice = 20%

a. One hawk needs 330 kJ of energy per day, which gives 330 kJ × 365 = 120,450 kJ per year

Let 'x' represent the number of weasels to support one hawk, we have;

0.3 × x = 120,450 kJ/year/(400 kJ) = 301.125

x = 301.125/0.3 = 1,003.75

The number of weasels required to support one hawk per year ≈ 1,003 weasels

The total weasels ≈ 1,003

ii) The number of mice needed, y = x/0.3 = 1,003.75/0.3 = 3,345.8[tex]\overline 3[/tex]

The total mice, y ≈ 3,345 mice

iii) The number of wheat flower needed, z = y/0.2

∴ The number of wheat flower needed, z = 3,345.8[tex]\overline 3[/tex]/0.2 ≈ 16,729.1[tex]\overline 6[/tex]

The total wheat plants ≈ 16,729.
