Question

The cells in the body can store only enough fuel for a one-minute walk or a five- to six-second sprint. a. true b. false

A) True
B) False

Answer 1

False. The cells in the body can store enough fuel for longer periods of physical activity.

Step-by-step explanation:

False

The cells in the body can store enough fuel for longer periods of physical activity. During aerobic respiration, cells break down glucose and other fuel sources to produce ATP, which is the energy currency that powers cellular function.

For a one-minute walk, the cells can rely on aerobic respiration to provide enough ATP. However, for a five- to six-second sprint, the cells use a different process called anaerobic respiration, which breaks down glucose without the need for oxygen but produces lactic acid as a by-product. This process can only sustain high-intensity activity for a short period of time.
