Answer:
The answer is A
Explanation:
Because available energy decreases as you go up
Answer:
False.
Explanation:
An Haemoglobin molecule is made up of 4-polypeptides, with each of the polypeptide chain containing an haem group. These haem group can bind with one oxygen atom each.
T<u>he binding of the first oxygen atom by the first haem group weakens the tertiary protein structure of Quaternary structure Hb, thus it makes it easier for the second Oxygen atom to bind faster, and the 3rd oxygen very fast and the 4th oxygen atom the fastest.These accelerated binding of the oxygen atoms, facilitated by the first binding O2, is called cooperative binding.It aids oxygen binding capacity and tranport functions of Hb,</u>
<u />
<u>Myoglobin is an oxygen storage protein in muscles, and not oxygen carrying molecule, It releases stored O2 only in condition of low oxygen supply</u>.It has one haem group in its molecule.Therefore its structural features can not carry out cooperative binding.
Answer: Option B
The concentration of protein in the postglomerular blood is high comparef with arterial blood because as water passes into the capsule, the concentration of protein in the blood will increase.
Explanation:
Kidneys are bean shaped organs present in veterbrates and it is located in the retroperitoneal space. Kidney filtration involves where blood passes through the afferent arterioles and enters the glomerulus where blood that can be filter like nitrogenous waste and water moves towards the glomerulus and nonfilterable substances such as cells and serum albumins pass out through efferent arterioles. Thee concentration of protein increases from arterial to the post glomerular because some of the water molecules diffuses to the filtrate therefore, reducing water concentration. This lead to increase in concentration of protein because water is not available to diffuse the protein.
d. carbohydrates store energy for a long time :)
