Question

the two main products of fermentation are? alcohol and lactic - acid aerobic and anaerobic muscle cells and bread mitochondria and chloroplasts how does the body of a runner keep up with the demand for energy when cellular oxygen levels are low? through energy production in the chloroplast through aerobic respiration in the plasma membrane through atp produced directly from sunlight through anaerobic respiration glycolysis means to... make sugar break down sugar repair cells break down cells which gas is removed from the atmosphere during cellular respiration? hydrogen oxygen nitrogen carbon dioxide

Explanation:

1. Fermentation has two main types producing alcohol and lactic - acid. Aerobic and anaerobic are types of respiration, not products. Muscle cells and bread are not products of fermentation. Mitochondria and chloroplasts are cell organelles.
2. When oxygen levels are low during cellular respiration in a runner's body, anaerobic respiration occurs to produce energy. Chloroplasts are in plant cells for photosynthesis. Aerobic respiration requires oxygen and doesn't occur in the plasma membrane. ATP is not produced directly from sunlight in animals.
3. Glycolysis is the process of breaking down sugar to produce energy. It doesn't make sugar, repair cells, or break down cells.
4. During cellular respiration, oxygen is taken in from the atmosphere and carbon - dioxide is released. Hydrogen and nitrogen are not involved in this gas - exchange process in the context of cellular respiration.

Answer:

1. Alcohol and lactic - acid
2. Through anaerobic respiration
3. Break down sugar
4. Oxygen
