Kreb’s Cycle is also called the ____ ____ Cycle

Answer 2

Citric Acid

Question 3

Kreb’s Cycle totals, per Pyruvic Acid:

Answer 3

Question 10

At the end of Step 2, as electrons are passed from 1 carrier to another, electrons are passed to ____, the FINAL ELECTRON ACCEPTOR

Answer 10

O₂

Question 11

Step 3 in Electron Transport Chain:

O₂ then binds to H⁺ to form ____

Answer 11

H₂O

Question 12

Step 4 in Electron Transport Chain:

Every time 2 HE electrons are transported down the chain, their ___ is used to pump H⁺ ions across the membane

Answer 12

Energy

Low

Question 15

Step 7 in Electron Transport Chain:

H⁺ ions move from (+) inside of the membrane to (-) outside of the membrane through ____ ______

Answer 15

ATP synthase

Question 16

Equation for ATP Synthase:

Answer 16
