What is the difference between a learned behavior and an inherited behavior? Give one example of each.
Mademuasel [1]

A learned behavior is a behavior that develops during an animal's lifetime. Tying one's shoes or solving a math problem are examples of learned behaviors. An inherited behavior is a behavior that an animal is born with. It does not have to be taught. For example, a bird can build a nest for the first time without any help.

Ivanshal [37]

The free energy for the oxidation of glucose to CO₂ and water is -686 kcal/mol and the free energy for the reduction of NAD+ to
Archy [21]

Answer: The main reason why only 2 molecules of NADH is formed during glycolysis when it appears that as many as a dozen could be formed is because during glycolysis,most of the free energy that are available from the oxidation of glucose remains in one of the products of glycolysis known as pyruvate which acts like glucose but doesn't undergo metabolism.

Glycolysis is the splitting of sugar molecules into useable/ manageable forms,it can also be seen as the aerobic catabolism of sugar inorder to produce energy in the form of ATP,NADH and PYRUVATE.The following are the products of glycolysis; pyruvate,2 molecules of ATP and 2molecules of NADH.

Pyruvate are used in aerobic respiration or anaerobic respiration if oxygen is not available.

Usimov [2.4K]

Answer:

<h2>It results in the production of more ATP in muscle cells.</h2>

Explanation:

i) An increase in the muscular stores of ATP and creatine phosphate.

ii). Increased levels of glycolytic enzymes which help the anaerobic glycolysis system to quickly

re-synthesize ATP.

iii). An increased lactate tolerance .

iv). An increase in myoglobin, which is responsible for extracting oxygen from the red blood cells and passing it to the mitochondria in the muscle cells, will allow for greater for aerobic energy production.
