Unit 7.4

Question 1

What is the order of stages of cellular respiration?

Answer 1

Glycosis, the link reaction, Krebs cycle and finally the electron transport chain

Question 2

What are the inputs and outputs of each stage?

Answer 2

Glycosis: Input= ADP and NAD+
Output= Pyruvate, ATP and NADH
Link reaction: Input= Pyruvate, COA and NAD+
Output= Acetyl-CoA, CO2 and NADH
Kreb cycle: Input= Acetyl-CoA, NAD+, ADP, and FAD
Output= CO2, NADH, ATP, and FADH2
ETC: Input= electrons, hydrogen
Output= ATP, water

Question 3

What is the location of each stage?

Answer 3

Glycosis = outside innear membrane space
Link reaction= innear membrane space
Kreb cycle= innear membrane space
ETC= innear membrane space

Question 4

What is the overall chemical equation for cellular respiration?

Answer 4

Glucose + O2 = CO2 + H2O + ATP

Question 5

What happens in your cells when they have no oxygen vs oxygen to generate ATP?

Answer 5

If they have no oxygen then the ETC will just clog up and it will not be able to take any more electrons through, aka no more ATP.

Question 5

How does the structure of the mitochondiran increase its function of making ATP?

Answer 5

Since it has a bunch of folds then it can fit a lot more ETC strands which can then create more and more ATP.
