Question

true or false questions: choose the correct answer from the choices for each question. 1. bacteria cannot perform cellular respiration because they do not have mitochondria t__ f 2. photosynthesis stores energy, while cellular respiration releases it t f 3. photosynthesis and cellular respiration can both occur underwater t f 4. running sprints and feeling your muscles burn is an indicator of aerobic respiration t f 5. photosynthesis has no effect on animals t f__

Explanation:

1. Bacteria can perform cellular respiration without mitochondria as they have enzymes on their cell - membrane for the process. So the statement is false.
2. Photosynthesis uses light energy to make glucose (stores energy), and cellular respiration breaks down glucose to release energy. This is true.
3. Some aquatic plants and algae can perform photosynthesis underwater, and many aquatic organisms can perform cellular respiration underwater. This is true.
4. Muscle burn during sprints is due to lactic - acid fermentation (anaerobic respiration), not aerobic respiration. So this is false.
5. Photosynthesis produces oxygen which is used by animals for respiration and also forms the base of the food - chain for animals. So this is false.
