Answer 1

Answer:

False. During physical exercise the oxygen concentration in the blood remains the same, with regard to rest.

Explanation:

In a healthy person, the concentration of oxygen —also called O₂ saturation— in arterial blood is in the order of 97 and 100%, both at rest and during exercise.

The concentration of oxygen in blood is a parameter that depends on proper respiratory function, and varies according to whether the blood is arterial or venous, where this percentage is lower.

The O₂ saturation in arterial blood allows to know the amount of oxygen that reaches the tissues and it is not a parameter that is modified with the exercise, although the respiratory and cardiac frequencies increase.

Answer 2
The correct answer is False

describe the three types of energy balance in the body and what each one is used for.​

Answers

Answer:

Explanation:

Lactic Acid System

The lactic acid system, also called the anaerobic glycolysis system, produces energy from muscle glycogen -- the storage form of glucose. Glycolysis, or the breakdown of glycogen into glucose, can occur in the presence or absence of oxygen. When inadequate oxygen is available, the series of reactions that transforms glucose into ATP causes lactic acid to be produced -- in efforts to make more ATP. The lactic acid system fuels relatively short periods -- a few minutes -- of high-intensity muscle activity, but the accumulation of lactic acid can cause fatigue and a burning sensation in the muscles.
