Chapter 8: Cellular Respiration

() loses electrons and () gains electrons

() loses electrons and () gains electrons

oxidation and reduction

what gets oxidized and what gets reduced

glucose and oxygen

If NAD gains an electron

it turns into NADH and it gets reduced

what two spots does NAD get reduced or picks up electrons in cellular respiration?

glycolysis and citric acid cycle

how do we make ATP?

through substrate level phosphorylation and oxidative phosphorylation

what waits for electrons to create energy

oxygen

at what cost can glycolysis still make energy without oxygen

at the cost of lactic acid forming at muscles

what percent of glycolysis is made from substrate level phosphorylation?

100%

what are the end products in glycolysis?

2, Pyruvate, 2 ATP, 2 NADH, 2 H+, and 2 H2O

how many ATPs are needed to start the process or for activation energy?

2

at the end of the glycolysis process, which product has the most energy./highest value?

pyruvate

what is the process called that turns pyruvate into Acetyl CoA?

the intermediary step

If you go around the citric acid cycle 4 times, how many of the products will there be?

8 CO2, 12 NADH, 4 ATP, 4 FADH, 0 electrons

for one glucose, there are how many ATP

36

most of the energy in oxidative phosphorylation is found in the () and ()

electron transport chain and chemiosmosis

what is the lowest level that electrons can be dropped off at?

FADH because it isn’t worth as much as NADH. It doesn’t have as much energy.

which part of cellular respiration does CO2 leave body from?

citric acid cycle

What’s the total energy range?

Both 36 or 38

what is the part of respiration that takes place at A?

Glycolysis

where in the cell does glycolysis occur?

in the cytoplasm

before we enter the krebs cycle, what must be added to pyruvate at location B?

Acetyl CoA

what are the names of the two separate parts of respiration located at C?

the electron transport chain and chemiosmosis

list the 3 sources of energy either captured or modified at location A.

glucose, pyruvate, and

exactly where in the cell does the krebs cycle produce energy?

in the mitochondria

how many ATPs are formed from one turn of the krebs cycle?

where in the mitochondria do the processes located at c take place?

inner mitochondrial membrane

each NADH is how many ATP?

3

each FADH is how many ATP?

2

what’s the ATP value at location D?

18

what’s the ATP value at location E?

4

What’s the total ATP captured from glycolysis and krebs cycle?

2 molecules of glucose times 38 atp is

76 atp

how many % of energy in glucose do we use? What happen to the rest?

40%. The rest gets lost to the environment as heat.
