Flashcards in Chapter 3 Deck (34):
1

Collective term for all biochemical reactions in a living organism

Metabolism

2

Whenever chemical bonds form/break

Chemical Reaction

3

Breaks molecules into smaller subunits

Decomposition

4

Decomposition reaction using water

Hydrolysis

5

Assembles large molecules from smaller subunits

Synthesis

6

Formation of complex molecules by removing water

Dehydration synthesis

7

All decomposition reactions in the body

Catabolism

8

All synthesis reactions in the body

Anabolism

9

Parts of the reacting molecules are moved around to create new products

Exchange reactions

10

Releases energy

Exergonic

11

Requires energy

Endergonic

12

What type of reactions are endergonic?

Synthesis

13

What type of reactions are exergonic?

Decomposition

14

Reactants become products at an equal rate of products becoming reactants

Reversible

15

Reactants are converted into products

Irreversible

16

Proteins that catalyze by lowering activation energy

Enzymes

17

Energy required to start a reaction

Activation energy

18

Reactants in enzymatic reactions

Substrates

19

Region in enzyme with a specific shape

Active Site

20

What are the steps in facilitating reactions?

Substrates bind to active site, enzyme substrate complex forms, temporary shape change occurs, product leaves active site

21

Organic molecules made of adenine and ribose

Adenosine

22

Where does glycolysis take place?

cytosol

23

No oxygen required

anaerobic

24

Glucose is broken down into 2 pyruvate

Glycolysis

25

How many ATP's are made in glycolysis per glucose?

2

26

Requires oxygen

aerobic

27

Pyruvate loses a carbon and binds with coenzyme A

Intermediate stage

28

Where does the intermediate stage take place?

mitochondria

29

Where does the citric acid cycle take place?

Mitochondria

30

How much ATP is formed in the citric acid cycle per glucose?

2

31

Sequence of proteins in the inner mitochondrial membrane, use hydrogen ions and electrons from previous steps to create H+ gradient; as hydrogen ions pass through ATP synthase ATP is formed

Electron transport system

32

How many ATP's are produced per glucose in the ETC per glucose?

34

33

How much water is produced in the ETC?

6

34

How much ATP is produced in the intermediate stage per glucose?
