a. If conversion of one mole of ATP to ADP P i releases about 7.3 kcal, roughly speaking, how many moles of ATP need to be produced per day in order for this energy need to be met? 3000 kcal/day divided by 7.3 kcal/mole of ATP 411 moles of ATP b. If the molecular weight of ATP is 573, how much would the required ATP weigh in kilograms?
Chapter 4 Section 4.1 Chemical energy and ATP The energy used for all cell functions is called ATP. There is a cycle of this energy production in the body cells. ATP is converted into ADP and the ADP is converted back to ATP. Adenosine tri phosphate (ATP)----

KEY CONCEPT All cells need chemical energy. All cells need chemical energy for their functions. The energy that your cells need comes indirectly from the food you eat. The chemical energy used by all cells is carried by a molecule called adenosine triphosphate, or ATP. ATP is a molecule that transfers energy from the breakdown of molecules in .

Reading: Chapter 2, section 3, Chapter 4, section 1 ! Topic 1: Energy and ATP (4.1) 1. Discuss why organisms need energy and how they obtain it. 2. Describe energy flow through an ecosystem. 3. Draw an ATP molecule and explain how ATP stores and releases energy. 4. Explain why ATP is referred to
ATP— The Free Energy Carrier 3 7. Consider Model 2. a. Is the process endothermic or exothermic? b. Recall that all bonds require energy to break, but energy is released when bonds are formed. With this in mind, explain why it is incorrect to say that the phosphoester bond in ATP . releases a large amount of energy when ATP turns into ADP .
