why do fast twitch muscles fatigue more quickly than slow twitch muscles?
they produce lactic acid
they have more mitochondria
they have more myoglobin

Explanation:

• First question: Aerobic cell respiration produces significantly more ATP per glucose molecule compared to lactic acid fermentation (which is a type of anaerobic respiration) and other anaerobic processes. Aerobic respiration goes through glycolysis, the Krebs cycle, and the electron - transport chain, generating about 36 - 38 ATP molecules per glucose. Anaerobic processes like lactic acid fermentation only produce 2 ATP per glucose.
• Second question: The products of aerobic cell respiration are carbon dioxide (\(CO_2\)), water (\(H_2O\)), and ATP. Oxygen (\(O_2\)) is a reactant, glucose (\(C_6H_{12}O_6\)) is also a reactant (or broken - down during the process), and lactic acid (\(C_3H_6O_3\)) is a product of anaerobic lactic acid fermentation.
• Third question: Fast - twitch muscles fatigue more quickly because they often rely on anaerobic metabolism (lactic acid fermentation). Lactic acid buildup causes fatigue. Slow - twitch muscles have more mitochondria (for aerobic respiration which is more sustainable) and more myoglobin (for oxygen storage, supporting aerobic metabolism).

Answer:

1. aerobic cell respiration
2. carbon dioxide
3. they produce lactic acid
