Lecture 8

Question 1

what is aerobic respiration?

Answer 1

Aerobic respiration is the breakdown of
glucose using oxygen, and yielding water,
carbon dioxide, and energy

Question 2

where does cellular respiration takes place ?

Answer 2

This process takes place in the cytoplasm, as

well as in the mitochondrion

Question 3

where does glycolysis takes place?

Answer 3

cytoplasm

Question 4

For each glucose molecule that undergoes

glycolysis, the cell gains…

Answer 4

2 ATP molecules available for immediate use
– 2 3-carbon molecules of pyruvate
– 2 reduced NAD+ molecules termed NADH

Question 5

what are 3 distinct

series of reactions of glycolysis?

Answer 5

priming reactions
cleavage reactions
oxidation reaction

Question 6

what is the priming reaction?

Answer 6

These first reaction require an input of
energy in order “prime” glucose for its future
energy productionIn 
these reactions 2 ATP molecules will be
used to “prime” glucose

Question 7

what is the cleavage reaction?

Answer 7

The phosphorylated glucose in cleaved into

two 3-carbon sugars

Question 8

what does the oxidation reaction in glycolysis?

Answer 8

The 3-carbon sugars are oxidized to
produce two NADH molecules, An organic phosphate is added to each of the
sugars
– Two ATPs are produced by substrate level
phosphorylation (for each 3-carbon sugar)

Question 9

know well the lecture 8 ?

Answer 9

yes
