How do the chemical reactions for photosynthesis and cellular respiration compare?
WHat is the key molecule that links the two reactions?
What happens to plants ability to undergo photosynthesis in the dark?does cellular respiration still take place?what gas is released?

1. The summary chemical reactions for photosynthesis and celular respiration are opposites. The reactants of one are the products of the other and vice versa.
2. The key molecule is glucose because photosynthesis builds glucose and respiration breaks down glucose.
3. Photosynthesis cannot happen in the dark because it runs on energy absorbed from light. Cellular respiration does happen in the dark because it does not rely on light, and because cells still need ATP energy from glucose in the dark. Oxygen gas is released from photosynthesis. Carbon dioxide is released from cellular respiration.

photosynthesis is the way that light is used as food. Cellular respiration is when the cells receive all the components to multiplicate or live.
the key molecule is Oxygen.
Plants that undergo photosynthesis tend to mutate to be able to surviv

glucose is the key molecule photosynthesis uses energy from light to make glucose from carbon dioxcide and water and realeases oxygen. during resperation cells use oxygen and release energy and carbon dioxcide from glucose. plants can not perform photosynthesis in the dark but resperation can continue untill glucose or oxygen is depleted

just do it yourself..you'll do better on the test..and you'll learn more..believe me..
