Question
plants carry out both photosynthesis and cellular respiration. which statement best compares the way these two processes handle energy?
photosynthesis converts light energy into chemical energy stored in glucose, while cellular respiration releases that stored energy to produce atp for cellular work
photosynthesis releases energy from glucose molecules to create atp, while cellular respiration stores light energy in the bonds of glucose.
photosynthesis captures energy directly into atp for long - term storage, while cellular respiration breaks down water molecules to release atp.
photosynthesis captures heat energy from sunlight to warm plant tissues, while cellular respiration stores that heat energy in chemical bonds.
the first law of thermodynamics, also known as law of conservation of energy, states that energy can neither be created nor destroyed; energy can only be transferred or changed from one form to another. trace the chain of energy conversions that must occur from the point at which sunlight strikes earths surface to the moment that energy is used to move your leg.
solar energy → glucose → atp → muscle contraction
solar energy → atp → glucose → muscle contraction
solar energy → glucose → muscle contraction → atp
solar energy → o2 → glucose → muscle contraction
- First question:
- Photosynthesis uses light energy to make glucose (stores chemical energy).
- Cellular respiration breaks down glucose to release energy for ATP (used for cellular work).
- Second question:
- Solar energy is converted to glucose via photosynthesis.
- Glucose is broken down in cellular respiration to make ATP.
- ATP is used for muscle contraction.
