Question

atp review

1. list the name and number of each molecule forming atp:
2. how do atp and adp differ in

(a) number of phosphate groups?
(b) number of ribose molecules?
(c) number of adenine molecules?
(d) amount of potential chemical energy?

1. what is required to transform adp to atp?
2. what is released when atp is transformed into atp?

5 your muscles require energy to move your body, just as your cells require energy to grow. what chemical directly supplies your muscles/cells with energy?

1. explain how an atp molecule is transformed into an adp molecule:
2. what process directly supplies your body with the energy it needs to change adp back to atp?

energy is released and used for work. energy is also supplied during cellular respiration. complete the diagram below by writtng in the words \energy released\ and \energy supplied by respiration\.

1. what molecule is used to supply energy for respiration?

Explanation:

1. ATP structure: Adenine (1), ribose (1), phosphate groups (3).
2. ATP vs ADP differences: Phosphate count (3 vs 2), same ribose/adenine, ATP has more energy.
3. ADP→ATP needs energy + phosphate.
4. Likely typo (ATP→ADP): Energy released.
5. ATP directly supplies cellular energy.
6. ATP loses a phosphate, releasing energy to form ADP.
7. ATP→ADP: energy released; ADP→ATP: energy supplied by respiration.
8. Glucose (or organic molecules) supplies energy for respiration.

Answer:

1. 1 adenine, 1 ribose, 3 phosphate groups
2. (a) ATP has 3, ADP has 2

(b) Both have 1
(c) Both have 1
(d) ATP has more

1. Energy and a phosphate group
2. Energy (assuming typo: ATP→ADP)
3. ATP
4. ATP loses one phosphate group, releasing energy, forming ADP
5. ATP→ADP arrow: energy released; ADP→ATP arrow: energy supplied by respiration
6. Glucose (or food molecules like carbohydrates)
