Answer:
Photosynthesis uses light energy to convert carbon dioxide and water into glucose and oxygen gas. Each molecule of glucose essentially “stores” up to 38 molecules of ATP which can be broken down and used during other cellular reactions. ATP, or adenosine triphosphate, is the form of chemical energy cells use to function. Cellular respiration is the complementary reaction to photosynthesis, because it is the reaction that cells use to break down glucose molecules and release ATP. The potential energy stored in the molecular bonds of glucose becomes kinetic energy after cellular respiration that cells can use to do work like move muscles and run metabolic processes.
Answer: B
Explanation: Researchers have induced differentiating cells to revert to being stem cells. According to Spradling, it has long been known that some specialized, or differentiated, cells in the body can revert to become stem cells to regenerate tissue under particular conditions
