Chapter 4--> Cells and Energy

Question 1

What is ATP?

Answer 1

The source of energy for use and storage at the cellular level

Question 2

What is ATP used for?

Answer 2

Energy in processes including ion transport, muscle contraction, nerve impulse propagation, substrate phosphorylation, and chemical synthesis

Question 3

What does ATP stand for?

Answer 3

Adenosine Triphosphate

Question 4

What is chemical energy?

Answer 4

Energy of chemical substances that is released when the substances undergo a chemical reaction and transform into other substances

Question 5

Where does the energy for making ATP come from?

Answer 5

It is the creation of ATP from ADP using energy from sunlight, and occurs during photosynthesis. ATP is also formed from the process of cellular respiration in the mitochondria of a cell

Question 6

What is the electron transport chain?

Answer 6

A series of four protein complexes that couple redox reactions, creating an electrochemical gradient that leads to the creation of ATP in a complete system named oxidative phosphorylation

Question 7

What are the components of the electron transport chain?

Answer 7

1. NADH –> NAD+
2. FADH2 –> FAD
3. ADT +P –> ATP
