M5 Respiration

Question 1

where does the glycolysis stage take place?

Answer 1

cytoplasm of cells

Question 2

where does the link reaction, krebs cycle and oxidative phosphorylation take place?

Answer 2

in the mitochondria

Question 3

How many molecules of ATP does 1 REDNAD make?

Answer 3

2.5

Question 4

how many molecules of ATP does 1 REDFAD make?

Answer 4

1.5

Question 5

what are 2 types of anaerobic respiration?

Answer 5

alcoholic fermentation and lactate fermentation

Question 6

what is the process of lactate fermentation?

Answer 6

pyruvate ——-lactate

rednad-nad

occurs in mammals

Question 7

what is the process of alcoholic fermentation?

Answer 7

pyruvate —-ethanal—–ethanol

decarboxylation occurs rednad to nad

occurs in yeast cells

Question 8

what is a respiratory substrate?

Answer 8

any biological molecule that can be broken down in respiration to release energy

Question 9

why do lipids have the highest energy value?

Answer 9

most atp is made in OP which requires hydrogen atoms from redNad and red FAD. more hydrogen atoms per unit of mass = more ATP produced when respired.

lipids contain the most hydrogen atoms per unit of mass

Question 10

what is the RQ value of lipids, carbohydrates and proteins?

Answer 10

lipids- 0.7
proteins-0.9
carbohydrates- 1

Question 11

RQ equation

Answer 11

volume of CO2 released/ volume of 02 consumed

Question 12

what do high RQ mean?

Answer 12

means that an organism is short of oxygen and is having to respire anaerobically as well as aerobically
