Which of the following statements are true about ATP? SELECT ALL THAT APPLY a ATP is used as an energy source by cells b ATP is produced during cellular respiration c ATP is a product of photosynthesis d ATP is only produced in plant cells e ATP is required for photosynthesis to occur \( \times \) a

Let's analyze each statement about ATP (adenosine triphosphate) to determine which are true: a. **ATP is used as an energy source by cells.** - **True.** ATP is often referred to as the energy currency of the cell, as it provides the energy needed for various cellular processes. b. **ATP is produced during cellular respiration.** - **True.** ATP is generated during cellular respiration, which includes glycolysis, the Krebs cycle, and oxidative phosphorylation. c. **ATP is a product of photosynthesis.** - **True.** ATP is produced during the light-dependent reactions of photosynthesis, where light energy is converted into chemical energy. d. **ATP is only produced in plant cells.** - **False.** ATP is produced in both plant and animal cells. All living cells require ATP for energy. e. **ATP is required for photosynthesis to occur.** - **True.** ATP is necessary for the Calvin cycle, which is part of photosynthesis, as it provides the energy needed to convert carbon dioxide into glucose. Based on this analysis, the true statements about ATP are: - a - b - c - e The false statement is: - d So, the correct answers are: **a, b, c, e**.
