Option A is correct. For skeletal muscle, there are 37 molecules of ATP produced from one Glucose-6-phosphate derived from glycogen, assuming the presence of the glycerol-3-phosphate shuttle.
<h3>How does skeletal muscle use ATP for the duration of exercise?</h3>
1. Contracting skeletal muscle is capable to use a quantity of intra- and extramuscular substrates to generate ATP at some point of exercise. These include creatine phosphate (CP), muscle glycogen, blood-borne glucose, lactate and free fatty acids (FFA), derived from either adipose tissue or intramuscular triglyceride stores.
<h3>What produces the most ATP for muscle contraction?</h3>
Aerobic respiratory produces giant amounts of ATP and is an environment friendly capability of making ATP. Up to 38 ATP molecules can be made for every glucose molecule that is damaged down. It is the desired approach of ATP production by body cells.

Polygenic traits are those traits that are controlled by more than one gene (poly- means many). The examples for polygenic traits are eyes colour, hair colour, human height, etc.
Pleiotropic traits are those traits that are controlled by one gene. For instance, if one gene controls two different traits, then those traits are pleiotropic traits. The example is gene for phenylketonuria and sickle-cell anemia.
Knowing and understanding how different traits are controlled (by one or by many genes) is important for <span>linking human genotypes to phenotypes.</span>
