Q

what is the second step of glycolosis

(G3P)

Q

What is the third step of glycosis

A

G3P release e- and H+ to an electron carrier
Phosphates removed (steps 1 & 4) and added to

ADP to form 4 ATP

6) Pyruvate has been made (3-C molecule)

7) 2 ATP are needed to start process, so net ATP = 2

Q

how do you start the Krebs cycle

A

Pyruvate loses a carbon as CO2

2) Acetyl CoA (2-C molecule) combines w/4-c

molecule to form citric acid (6-C molecule)

3) C & e- released making CO2 and NADH

4) 5-C loses another C and makes NADH and ATP

5) 4-C molecule is recycled making FADH2 and

NADH

Q

FADH2

A

pretty much NADH just a dfferent chemical make up
