What is the primary goal related to ATP in the context of physical activities?

• To store ATP for future use

• To provide enough ATP to fuel activities

• To convert ATP into ADP

• To reduce ATP production

Which enzyme is involved in the conversion of PC and ADP to ATP and C?

• Amylase

• Lipase

• Creatine kinase

• Pepsin

What is the role of glycogen in the metabolic process shown?

• It breaks down into amino acids

• It converts into fatty acids

• It is stored as protein

• It breaks down into glucose

Do human beings have the physiological capability to sustain 0.7 moles ATP/min levels of physical activity?

• Yes, with proper training

• No, it's beyond human capability

• Only under specific conditions

• Yes, naturally

What do we absolutely need to have going for us in order to meet the specific energy demand of 0.7 moles ATP/min?

• Adequate hydration

• Sufficient oxygen supply

• High carbohydrate intake

• Strong muscle mass

Do we have access to aerobic energy pathways immediately?

• Yes, instantly

• No, it takes time

• Only during rest

• Only after warming up

What does VO₂ represent in the context of exercise physiology?

• Volume of oxygen consumed

• Volume of carbon dioxide produced

• Volume of blood pumped by the heart

• Volume of air inhaled

What happens to VO₂ during continuous exercise according to the graph?

• It decreases steadily

• It remains constant

• It increases and reaches a steady state

• It fluctuates randomly

What is VO₂ max?

• The minimum oxygen consumption during rest

• The maximum oxygen consumption during exercise

• The average oxygen consumption during sleep

• The oxygen consumption at the start of exercise

In the incremental exercise test, what happens to VO₂ as work rate increases?

• VO₂ decreases

• VO₂ remains constant

• VO₂ increases

• VO₂ decreases and then increases
