Pre AP Cell Energy Review 1. Explain how energy is stored and released in a molecule of ATP. 2. Explain the difference between anabolic pathways and catabolic pathways and identify the type of pathway of photosynthesis and respiration. 3. Explain how the amount of ATP is indirectly related to the amount of calories per gram. 4. Explain the difference between photosynthesis and chemosynthesis in energy conversion for autotrophs and where you would expect to find chemosynthetic autotrophs. 5. What is the chemical equation for photosynthesis

Respuesta :

1. The ATP molecule can store energy while attaching ADP to the terminal phosphate group. The energy is released when the phosphate group from the ATP is broken down and inorganic phosphate is released.

2. Anabolic pathway involves the use of ATP to synthesize large molecules. However, catabolic pathway involves the breaking down of larger molecules and release energy. Therefore, Photosynthesis is the anabolic pathway and respiration is the catabolic pathway.

3. An ATP molecule when hydrolyzed releases 7.5 KCal of energy.

4. Both chemosynthesis and photosynthesis are the processes of producing food. However, photosynthesis requires sunlight as the source of energy and chemosynthesis requires chemical energy.

5. The chemical equation for photosynthesis is 6CO₂ + 6H₂O + energy - C₆H₁₂O₆ + 6O₂
