Answer 1

Aerobic or "with oxygen" exercises provide cardiovascular conditioning. The American Heart Association recommends a minimum of 30 minutes of cardiovascular exercise 5 to 7 days per week. Don't forget warm-up, cool-down and stretching exercises in your aerobic exercise session.

What is aerobic exercise?

Aerobic exercise provides cardiovascular conditioning. The term aerobic actually means "with oxygen," which means that breathing controls the amount of oxygen that can make it to the muscles to help them burn fuel and move.

Answer 2

Answer:

(A) (a)

(B) (d)

(C) (c)

(D) (c)

(E) (b)

Explanation:

• Aerobic respiration is the process of breaking down food molecules while using oxygen. The main respiratory substrate and the chemical typically employed for respiration is glucose. Energy is released from glucose through oxidation.
• During anaerobic respiration, glucose is only partially oxidized. As a result, only about a twentieth of the energy generated during aerobic respiration is released during the reaction.
• Without oxygen, most creatures cannot respire. However, some organisms and tissues can carry on respiring even if the oxygen supply runs low. These tissues and organisms carry out anaerobic respiration.
• Although animal muscles may breathe anaerobically for brief periods of time, it is preferable to continue breathing in order to be able to run away from danger or compete in a race.
• Lactic acid is produced via the conversion of muscle glucose:
• glucose----> lactic acid + energy released.
