Harvesting Energy in Cells

Question 1

Process by which cells break down organic compounds and produce ATP

Answer 1

Cellular respiration

Question 2

What is the equation for cellular respiration

Answer 2

organic compounds + O2 = CO2 + water + ATP

The products of cell respiration are the reactants in photosynthesis and the products of photosynthesis are reactants in cellular respiration.

Question 5

Where does cellular respiration occur?

Answer 5

cytosol of the mitochondria

Question 6

When given O2 and glucose, cellular respiration produces …

Answer 6

ATP, CO2, H2O

Question 7

What does photosynthesis use and produce?

Answer 7

it uses CO2 and H2O and produces O2 and glucose

Question 8

What does cellular respiration use and produce?

Answer 8

It uses O2 and glucose and produces CO2 and H2O

Question 9

Where is photosynthesis located?

Answer 9

stroma of chloroplast

Question 10

What are the two possible pathways of a cell getting energy?

Answer 10

Cellular respiration and Fermentation

Question 11

What is the process of cellular respiration?

Answer 11

organic compounds–>glycolysis –> pyruvic acid + ATP –> aerobic respiration –> CO2 + H2O –> ATP

Question 12

organic compounds–>glycolysis –> pyruvic acid + ATP –> aerobic respiration –> CO2 + H2O –> ATP (what pathway)

Answer 12

cellular respiration

Question 13

What is the process of fermentation?

Answer 13

organic compounds –> glycolysis –> pyruvic acid + ATP –> anaerobic pathways –> lactic acid, ethyl alchol, or other compounds

Question 14

organic compounds –> glycolysis –> pyruvic acid + ATP –> anaerobic pathways –> lactic acid, ethyl alchol, or other compounds (what process)

Answer 14

fermentation

Question 15

What pathway does glycolysis occur in?

Answer 15

cellular respiration and fermentation

Question 16

Where is glycolysis located in?

Answer 16

cytosol

Question 17

What is the net yield of glycolysis?

Answer 17

2 ATP per 1 glucose

Question 18

What is the process of glycolysis?

Answer 18

Two ATP molecules are used to break glucose into smaller units. A phosphate group is added to the 6 carbon compound. Each three carbon compound reacts with a phosphate group. Hydrogen atoms are transferred to NAD+, producing NADH. Each thrree carbon sugar is converted to a 3 carbon molecule of pyruvate. Four ATP molecules are produced.

Question 19

When does fermentation occur?

Answer 19

When there is no oxygen

Question 20

What happens when there is no oxygen?

Answer 20

Fermentation occurs

Question 21

What is the process of fermentation?

Answer 21

pyruvic acid –> lactic acid, ethyl alcohol, NAD+

Question 22

what can stop fermentation being used and make glycolysis continue?

Answer 22

when NAD+ is made

Question 23

What are the two types of fermentation?

Answer 23

lactic acid and alcoholic fermentation

Question 24

What is the difference between Lactic acid and alcoholic?

Answer 24

Lactic turns pyruvic acid into a three carbon compound while alcoholic turn pyruvic into ethyl alcohol and CO2

Question 25

What is the process of lactic acid?

Answer 25

6cs (glucose) --> glycolysis --> 3cs (pyruvic acid) | --> 3cs (lactic acid)

Question 26

what is the process of alcoholic fermentation?

Answer 26

6cs (glucose) --> glycolysis --> 3cs (pyruvic acid) | --> CO2 and 2cs (2 carbon compound) --> 2cs (ethyl alcohol)

Question 27

how much percent of the energy available is captured as ATP through glycolysis

Answer 27

2 percent

Question 28

The energy in glucose in fermentation is held in ...

Answer 28

pyruvic acid

Question 29

glycolysis alone or as a part of fermentation =

Answer 29

not very efficient

Question 30

What are the stages of aerobic respiration?

Answer 30

krebs cycle and electron transport chain

Question 31

where is the krebs cycle loacted?

Answer 31

mitochondrial matrix

Question 32

what does the krebs cycle make?

Answer 32

NADH

Question 33

the electron transport chain is located in the ...

Answer 33

inner membrane

Question 34

the electron transport chain turns ...

Answer 34

NADH --> ATP

Question 35

What is the process of the Krebs Cycle?

Answer 35

Pyruvic acid + Co-enzyme A --> Acetyl CoA

Question 36

What is the last stage of cellular respiration

Answer 36

electron transport chain

Question 37

What are the three stages of cellular respiration

Answer 37
