What process do fast twitch fibers primarily use to synthesize ATP?

• Aerobic respiration

• Glycolysis

• Oxidative phosphorylation

• Kreb cycle

How do slow twitch fibers primarily produce ATP?

• By breaking down proteins

• Utilizing oxygen to break down carbohydrates and fats

• Through glycolysis without oxygen

• By converting glycogen directly into ATP

What is a key characteristic of slow twitch fibers?

• They are larger in diameter

• They store less glycogen

• They fatigue quickly

• They contract with less force

What adaptation occurs in fast twitch muscle fibers with exercise?

• They lose their ability to store glycogen

• They convert into slow twitch fibers

• They undergo hypertrophy

• They decrease in number
