How do the sequence and composition of amino acids in a protein influence how a protein folds up

Answer:

See the explanation below, please.

Explanation:

The amino acid sequence of a protein will determine the interactions inside and with the environment (that is, it will influence the conformations that are adopted at physiological temperature: the degrees of freedom). Example: the proline amino acid (Pro) has a cyclic structure, which implies a limitation in the random movement of the polypeptide chain.

In proteins, the primary structure determines the sequence of the amino acid sequence of the polypeptide chain (amount of amino acids present and their order by means of peptide bonds).

Do you think it is possible for scientists to incorporate chloroplasts into the skin cells of humans? What would this mean for h

Alisiya [41]

Similarly to mitochondria on which the animals and fungi rely upon, the chloroplasts are the solar-power plants of the plant cell. With the advancement in the field of genetics and biotechnology, it may be feasible for scientists to incorporate chloroplasts into human skin cells. However, there may be few issues, which the human beings would have to encounter with, these are as follows:

1. The immune system of the humans may attack the chloroplasts, but maybe they would be safe if they are present within the cell.

2. As the skin of the humans would be undergoing the process of photosynthesis, then they would have to be in green color, thus, the melanocytes of the skin would have to be engineered in order to generate another pigment.

3. The humans may get skin cancer and sunburns when they would be out feeding on sunlight, that is, the ultraviolet part of the sunlight would cause the destruction of the living cells.

4. In order to undergo the reaction of photosynthesis, the humans would require more water than usually required by a normal human being, and this could be a disadvantage in a desert surrounding.

5. The process would not help to generate much energy for an active species like humans, as the daily energy requirements for a human being would be attained by absorbing around 10000 kJ of energy, that is, around 150 hours in a day of sitting in the Sun, which is impossible.

Which energy is affected by an object's mass?

statuscvo [17]

Answer:

A potential

B kinetic

Explanation:

Kinetic energy can be defined as an energy possessed by an object or body due to its motion.

Mathematically, kinetic energy is given by the formula;

$K.E = \frac{1}{2}MV^{2}$

Where, K.E represents kinetic energy measured in Joules.

M represents mass measured in kilograms.

V represents velocity measured in metres per seconds square.

Potential energy can be defined as an energy possessed by an object or body due to its position.

Mathematically, potential energy is given by the formula;

$P.E = mgh$

Where, P.E represents potential energy measured in Joules.

m represents the mass of an object.

g represents acceleration due to gravity measured in meters per seconds square.

h represents the height measured in meters.

Both potential and kinetic energy is affected by an object's mass.

what is the North Star? does it move in the night sky? how do the stars and constellations move with the respect to this tar? wh

Solnce55 [7]

1. <span>The North Star, or Polaris, is the brightest star in the constellation Ursa Minor, the little bear (also known as the Little Dipper). As viewed by observers in the Northern Hemisphere, Polaris occupies a special place. The point in the night sky where the projection of the earth's axis lies is known as the North Celestial Pole (NCP). As the earth rotates on its axis (once every 24 hours), the stars in the northern sky appear to revolve around the NCP. Polaris lies roughly one half degree from the NCP, so this particular star appears to remain stationary hour after hour and night after night. 2.</span>
