Chapter 7 Lesson 3

Question 1

What is the definition of metabolism?

Answer 1

Chemical reactions inside of cells that turn nutrients into energy

Question 2

What is the definition of anabolic?

Answer 2

Causes reactions which make larger molecules out of smaller ones

Question 3

What is the definition of catabolic?

Answer 3

Causes reactions that break down larger molecules into smaller ones

Question 4

What is the definition of exergonic?

Answer 4

Causes reactions which release more energy than they require

Question 5

What is the definition of endergonic?

Answer 5

Causes reactions that require more energy than they release

Question 6

What is the definition of hydrolosis?

Answer 6

The breaking down of a chemical using water

Question 7

What happens first in an ATP/ADP cycle, anabolic (endergonic) reactions or catabolic (exergonic) reactions?

Answer 7

Anabolic (Endergonic)

Question 8

Briefly describe the ATP/ADP cycle

Answer 8

First the molecules go through anabolic reactions to turn into ATP and the they go through phosphate transfer into catabolic reactions which turns it into ADP and this process repeats itself

Question 9

Is an anabolic reaction exergonic or endergonic?

Answer 9

Endergonic

Question 10

Is a catabolic reaction exergonic or endergonic?

Answer 10

Exergonic
