cellular respiration

Question 1

where does all glucose on earth come from?

Answer 1

photosynthesis

Question 2

what is the equation for photosynthesis?

Answer 2

6 co2+6 h2o+sunlight energy= c6h12o6+6 o2

Question 3

what is the equation for cellular respiration?

Answer 3

c6h12o6+6 o2= 6 co2+6 h2o+ATP

Question 4

what is oxidized in cellular respiration?

Answer 4

c6h12o6–> 6 co2

Question 5

what is reduced in cellular respiration?

Answer 5

6 o2–> 6 h2o

Question 6

what are the steps of cellular respiration?

Answer 6

1. glycolysis
2. intermediate step
3. Krebs cycle
4. electron transport chain

Question 7

what happens in glycolysis?

Answer 7

2 pyruvate are created and 2 ATP (anaerobic)

Question 8

what happens in the intermediate step?

Answer 8

pyruvate is oxidized to acetyl CoA

Question 9

what happens in the citric acid cycle?

Answer 9

Inputs: acetyl CoA, oxaloacetate, water
outputs: co2, NADH, FADH2, 2ATP
(anaerobic)

Question 10

what happens in the ETC?

Answer 10

(mitocondria, aerobic) 34 ATP produced

Question 11

what is lactic acid fermentation?

Answer 11

making ATF without oxygen, glycolysis only
oxidize NADH and reduce pyruvate (opposite of glycolysis)

Question 12

what is alcohol fermentation?

Answer 12

oxidize NADH and reduce pyruvate in the presence of yeast.
makes co2, and ethyl alcohol
