- Which of the following statements is NOT true? None of the other four answers (all are true) The energy required to cause a chemical reaction to occur is called the activation energy Decomposition (degradation, catabolic) reactions are usually endergonic Chemical reactions in living cells are catalyzed by enzymes Enzymes increase the probability that a chemical reaction will take place by lowering the activation energyarrow_forwardDiscuss how energy controls what happens in both the biological and physical environment.arrow_forwardThe molecule that each cell uses as fuel to directly power its cellular processes is called: Glucose O Glycogen O Protein Saturated fat ATParrow_forward
- Light is a form of electromagnetic energy. The electromagnetic spectrum is made of various forms of electromagnetic energy, such as x-rays, UV, and microwaves. Visible light is used in photosynthesis. What is visible light? How are energy and wavelength related to each other? The overall goal of photosynthesis is to make harness the energy of the sun and store it in the chemical bonds of “food.” In your own words describe the goals of the two sets of reactions of photosynthesis: a.The goal of the light reactions b.
