6A-aerobic cellular respiration

Question 1

cellular respiration

Answer 1

 the process by which cells create usable energy in the form of ATP from a series of biochemical reactions, involving the breakdown of glucose
- break down large molecules and produce substantial amounts of the high-energy molecule ATP

Question 2

aerobic cellular respiration equation

Answer 2

C6H12O6+ 6O2 —–> 6CO2 + 6H20 + 30 or 32 ATP

Question 3

Glycolysis

Answer 3

location: cytosol of cell
role: pyruvate and NADH that are produced will go on to help make even more ATP
-glucose breaks down into two pyruvate molecules, creating two ATP and two NADH molecules in the process

Question 4

GYCOLOSIS INputs

Answer 4

1 glucose ((C6H12O6)
2 ADP + 2 Pi
2 NAD + 2 H

Question 5

GYCOLYSIS OUTputs

Answer 5

2 pyruvate
2 ATP
2 NADH

Question 6

Krebs cycle

Answer 6

locations: mitochondria
role: generates lots of high-energy electron and proton carriers, NADH and FADH2, can used in ETC
-t produces four CO2, two FADH2, six NADH, and two
ATP for every two pyruvate molecules created via glycolysis.

Question 7

link reaction

Answer 7

pyruvate is transported matrix of the
mitochondria, then combines w/ coenzyme A (CoA) = acetyl-CoA.
- also releases carbon dioxide, is a waste product is exhaled and produces NADH can be used later in ETC

Question 8

KREBS CYCLE INputs

Answer 8

2 acetyl-CoA
(derived from 2 pyruvate)
2 ADP + 2 Pi
6 NAD+ + 6 H
2 FAD + 4 H

Question 9

KREBS CYCLE OUTputs

Answer 9

4 carbon dioxide (co2)
2 ATP
6 NADPH
2 FADH2

Question 10

KREBS CYCLE process

Answer 10

• krebs series of 8 reactions that extract energy from the ‘acetyl-’ (two-carbon) component of acetyl-CoA- breaking git down and allow coenzyme A mole to be recycled back to use in link reaction
• by break down of acetyl-CoA- protons and high energy electrons released. - these protons and electrons loaded into NAD and FAD mole to make high energy coenzymes NADPH and FADH2
• krebs makes 2 CO2 for every one acetyl-CoA MOLE. - when add to 1 CO2 mole made from each 2 pyruvates undergoing link react- total 6 co2 moles produced every of glucose mole.
• small amount of atp produced

Question 11

ELECTRON TRANSPORT CHAIN (etc)

Answer 11

location: inner membrane (cristae) of mitochondria
role: converts high-energy coenzymes NADH and FADH2 back to NAD+ and FAD forms, then recycled use in glycolysis and the Krebs cycle
-energy from the electrons unloaded by NADH and FADH2 generates a proton gradient that drives significant ATP production.

Question 12

ETC INputs

Answer 12

26 or 28 ADP + Pi
10 NADH
2 FADH2
6 Oxygen (O2)

Question 13

ETC OUTputs

Answer 13

26 or 28 ATP
10 NAD + 10 H
2 FAD + 4 H
6 water (H2O)

Question 14

total atp produced from aerobic cellular respiration

Answer 14

Combined with 2 ATP produced in glycolysis and 2 ATP from Krebs cycle, = total of 30 or 32 ATP can be produced from each original glucose molecule.
- committed to aerobic cellular respiration
