09 - Muscle Tissue: Respiration - Hypertrophy

Front

What is anaerobic respiration?

Back

A metabolic process that occurs without oxygen, producing energy through the breakdown of glucose, resulting in byproducts like lactic acid.

Front

What causes muscle fatigue?

Back

Muscle fatigue occurs when the muscle can no longer contract even when it is stimulated or when it is not able to fully contract.

Front

What is hypertrophy?

Back

Hypertrophy is the increase in muscle size and strength due to exercise, particularly resistance training.

Front

What is creatine phosphate used for in muscle metabolism?

Back

Creatine phosphate is used to regenerate ATP after stored ATP is depleted during high-intensity exercise.

Front

What are the byproducts of anaerobic glycolysis?

Back

Anaerobic glycolysis produces ATP, pyruvic acid, and lactic acid if pyruvic acid accumulates.

Front

What is the oxygen debt?

Back

Oxygen debt is the extra amount of oxygen that must be taken in by the body to restore oxygen balances for aerobic respiration after intense exercise.

Front

What is the role of lactic acid in muscle fatigue?

Back

Lactic acid accumulates in muscles during anaerobic respiration, contributing to the sensation of fatigue and muscle soreness.

Front

How does aerobic respiration differ from anaerobic respiration?

Back

Aerobic respiration requires oxygen and produces more ATP per glucose molecule compared to anaerobic respiration, which does not require oxygen.

Front

What is atrophy in muscle tissue?

Back

Atrophy is the reduction in size, tone, and power of a muscle due to disuse or disease.

Front

What is the primary energy source for muscle contraction during the first few seconds of intense exercise?

Back

The primary energy source is stored ATP, followed by creatine phosphate.
