A sprinter's stored ATP is used up about two seconds after the start. Which supply regenerates ATP fastest over the next ten seconds?
A cyclist rides all-out for about 45 seconds, too hard for mitochondria to meet the ATP demand. Which pathway supplies most of the rapid ATP?
A hiker keeps a steady moderate pace for two hours. Which pathway can supply ATP for that duration?
Which ATP source makes ATP in a single enzyme reaction, which makes it faster than any multistep pathway?
Which pathway nets only 2 ATP from each sugar molecule it breaks down and produces lactic acid as a by-product?
Which pathway yields about 30 or more ATP from each glucose and releases carbon dioxide and water as waste?
Creatine phosphate is stored in skeletal muscle fibers. What is its job during a brief maximal contraction?
Myoglobin is abundant in many slow, fatigue-resistant fibers. What does myoglobin do there?
Glycogen granules are packed into skeletal muscle fibers. What job do they serve during exercise?
Triglyceride droplets are common in slow oxidative fibers. What do they store for long-duration work?
A small ATP reserve is present in a resting muscle fiber before contraction starts. What does that reserve do first?
During repeated all-out contractions, pH inside fibers drops and power falls. Which change best explains the fatigue?
After many short jumps with little rest, an athlete's first-step power fades. Which depleted reserve explains the loss of explosive ATP regeneration?
Near the end of a long race, a runner's muscle glycogen is very low. What consequence would directly contribute to fatigue?
A sustained wall sit compresses blood vessels in the working thigh muscles. What change can make the fibers fatigue?
After a hard 400-meter run, extra O2 is taken in while lactate levels fall. What recovery process uses much of that O2?
After a heavy set of lifts, phosphagen stores are low. What is some of the repaid O2 used to restore?
During a sprint, oxygen bound to a muscle pigment is unloaded. What does extra O2 help do during recovery?
A muscle's small ATP pool is partly depleted after repeated contractions. What does repaid O2 help restore?
After exercise, ion pumps return Na+, K+, and Ca²⁺ to resting distributions. What is repaid O2 used for in that process?
