In yeast

Question 5

What is first step in cellular respiration?

Answer 5

Glycolysis

Question 6

What happens during glycolysis?

Answer 6

Glucose (6c) broken into pyruvic acid

Question 7

How much ATP does it take to split Glucose?

Answer 7

2 ATP

Question 8

How much ATP does glycolysis produce?

Answer 8

4 ATP

Question 9

What else does glycolysis produce besides ATP?

Answer 9

NAD+ to NADH

Question 10

Formula for alcoholic fermentation?

Answer 10

Alchol + CO2 + NAD + (yeast) = alcholic fermenartion

Question 11

Formula for lactic acid fermentation?

Answer 11

Lactic acid + NAD + (many bacteria) + animals like us = lactic acid fermentation

Question 12

T or F, fermenation regenerates NAD+

Answer 12

TRUE

What is Krebs Cycle aka?

Answer 13

The Citric Acid Cycle

Question 14

Where does fermenation occur?

Answer 14

v

Question 15

WHat happens in the Krebs Cycle?

Answer 15

the 2 pyruvic acids are broken, releasing CO2 and 2 ATP’s, (one from each pyruv)

How many calories make up one Calorie?

Answer 16

1000

Question 17

Where does glycolysis take place?

Answer 17

In the cell membrane

Question 18

What is NAD+

Answer 18

an electron carrier

Question 19

How does NAD+ turn into NADH?

Answer 19

accepts pair of electrons and a hydrogen ion

Question 20

What is fermentation?

Answer 20

process that releases energy from food molecules by producing ATP in absence of oxygen

Question 21

Why is Krebs cycle aka the citric cycle?

Answer 21

citrtixc acid is the first molecule produced

Question 22

What does 1 pyruvic acid produce in kreb cycle?

Answer 22

4 NADH, 1 FADH2, 1 ATP

Question 23

What happens when carbon dioxide is produced in breaking down of pyruvs?

Answer 23

it is released into the umgebung

Question 24

What is the electron transport chain?

Answer 24

set of proteins in the mitochondria

Question 25

What does electron transport chain use the high energy electron for?
