Why is anaerobic respiration less efficient than aerobic?

• aerobic respiration consumes less oxygen

• aerobic respiration consumes less substrate

• aerobic respiration produces more ATP

• aerobic respiration can use both oxygen or carbon dioxide while anaerobic uses only oxygen

The enzyme sucrase breaks down sucrose (table sugar) into monosaccharides (simple sugars) but does not break down starch. Why?

• consists of fructose

• acts only on certain specific substances

• becomes part of the reaction

• decreases reaction rates

This diagram shows an experimental setup containing an aquatic plant, elodea, gas collection equipent, and a light source. Which gas bubbles are being collected?

• carbon dioxide, because it is a waste product of photosynthesis

• water vapor, because it is a waste product of photosynthesis

• nitrogen, because it is a waste product of photosynthesis

• oxygen, because it is a waste product of photosynthesis

Lactic acid fermentation is a way to recycle a molecule that is needed to make ATP in glycolysis, the first step of cellular respiration. Which of the following can use lactic acid fermentation?

• human muscle cells get tired and sore

• human skills cells mutate

This process is used to make bread rise.

• Photosynthesis

• lactic acid fermentation

• alcohol fermentation
