Question

10 multiple answer 1 point what is the difference(s) between aerobic and anaerobic cellular respiration? select all that are true. aerobic produces more atp than anaerobic cell respiration aerobic cell respiration uses glucose to make atp; anaerobic uses co₂ to make atp aerobic cell respiration occurs only in muscle cells; anaerobic cell respiration can occur in all cells aerobic requires oxygen; anaerobic cell respiration does not

Explanation:

• Aerobic respiration occurs in the mitochondria and requires oxygen. It produces a large amount of ATP (about 36 - 38 ATP molecules per glucose molecule). Anaerobic respiration occurs in the cytoplasm and does not require oxygen. It produces a small amount of ATP (2 ATP molecules per glucose molecule in glycolysis, and in some cases like lactic acid fermentation or alcoholic fermentation, the additional ATP production is minimal compared to aerobic respiration).
• Let's analyze each option:
• Option 1: Aerobic produces more ATP than anaerobic
• Aerobic respiration has a higher ATP yield. Glycolysis (common to both aerobic and anaerobic in some cases) produces 2 ATP. In aerobic respiration, after glycolysis, the Krebs cycle and electron - transport chain (which require oxygen) produce a large number of ATP. In anaerobic respiration (e.g., lactic acid fermentation in animals), after glycolysis, the process regenerates NAD+ but does not produce a significant amount of additional ATP. So, aerobic produces more ATP than anaerobic.
• Option 2: Aerobic uses glucose to make ATP; anaerobic uses CO₂ to make ATP
• Both aerobic and anaerobic respiration use glucose as the starting substrate (in most cases). Aerobic respiration breaks down glucose completely in the presence of oxygen to produce ATP, CO₂, and water. Anaerobic respiration (e.g., lactic acid fermentation) also starts with glucose. It is incorrect to say that anaerobic uses CO₂ to make ATP.
• Option 3: Aerobic occurs only in muscle cells; anaerobic cell respiration can occur in all cells
• Aerobic respiration occurs in most eukaryotic cells (not just muscle cells) that have mitochondria and are in an oxygen - rich environment. Anaerobic respiration (e.g., lactic acid fermentation) occurs in muscle cells under strenuous exercise (when oxygen is limited), but there are other types of anaerobic respiration (e.g., alcoholic fermentation in yeast) that occur in non - muscle cells. Also, not all cells can perform anaerobic respiration. For example, some aerobic bacteria cannot perform anaerobic respiration in the traditional sense of the word (they may have alternative non - respiratory energy - generating mechanisms in the absence of oxygen, but it is not the same as the anaerobic respiration in eukaryotic cells).
• Option 4: Aerobic requires oxygen; anaerobic respiration does not
• This is a correct statement. Aerobic respiration has the final electron acceptor as oxygen in the electron - transport chain. Anaerobic respiration (e.g., lactic acid fermentation) does not use oxygen as the final electron acceptor.

Answer:

A. Aerobic produces more ATP than anaerobic; D. Aerobic requires oxygen; anaerobic respiration does not
