Q

Proteins that catalyze by lowering activation energy

A

Enzymes

17
Q

Energy required to start a reaction

A

Activation energy

18
Q

Reactants in enzymatic reactions

A

Substrates

19
Q

Region in enzyme with a specific shape

A

Active Site

20
Q

What are the steps in facilitating reactions?

A

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

21
Q

Organic molecules made of adenine and ribose

A

Adenosine

22
Q

Where does glycolysis take place?

A

cytosol

23
Q

No oxygen required

A

anaerobic

24
Q

Glucose is broken down into 2 pyruvate

A

Glycolysis

25
Q

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

A

2

26
Q

Requires oxygen

A

aerobic

27
Q

Pyruvate loses a carbon and binds with coenzyme A

A

Intermediate stage

28
Q

Where does the intermediate stage take place?

A

mitochondria

29
Q

Where does the citric acid cycle take place?

A

Mitochondria

30
Q

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

A

2

31
Q

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

A

Electron transport system
