The Krebs Cycle

What is the first step of the Krebs Cycle?

Pyruvic acid is converted to acetyl Co-A as it enters the mitochondria

What is the second step of the Krebs Cycle?

Citric acid is the first molecule formed

What is the third step of the Krebs Cycle?

Citric acid is broken down and new molecules produced

What molecules are produced in the Krebs Cycle?

CO2, ATP, NADH, FADH2

What molecule is used in the Krebs Cycle?

acetyl Co-a

Where does the Krebs cycle occur?

the mitochondria

Cellular Respiration

The process by which mitochondria break down glucose to make ATP

What process does all cellular respiration start with?

Glycolysis

Aerobic respiration

requires oxygen & carried out by plants, animals and some bacteria

What are the major steps of aerobic respiration?

Glycolysis, The Krebs Cycle, ETP

How many ATP are formed in aerobic respiration?

36-38

How many ATP are formed during glycolysis?

2

How many ATP are formed during the Kreb's Cycle?

2

How many ATP are formed from the ETC?

32-34

What is the equation for Respiration?
