biology chapter 6: cell's chemistry energy

Question 1

two types of cellular respiration

Answer 1

aerobic
anaerobic

Question 2

aerobic cellular respiration

requires what?

Answer 2

requires O2

Question 3

anaerobic cellular respiration

deosnt require what?

Answer 3

doesnt require O2

Question 4

ultimate source of energy

Answer 4

sun

Question 5

photosynthesis requires what

Answer 5

sunlight

Question 6

cellular respiration requires what?

Answer 6

photosynthesis

Question 7

what two processes are in a cycle with each other?

Answer 7

photosynthesis
cellular respiration

Question 8

photosynthesis reactants

there are two

Answer 8

carbon dioxide
water

CO2 and H2O

Question 9

photosynthesis products

Answer 9

oxygen and glucose

O2 and C6H12O6

Question 10

from reactant to products in photosynthesis, what is the yield?

Answer 10

sunlight

Question 11

cellular respiration reactants

Answer 11

oxygen and glucose

O2 and C6H12O6

Question 12

cellular respiration products

Answer 12

carbon dioxide
water

CO2 and H2O

Question 13

from reactions to product in cellular respiration, what is the yield?

Answer 13

ATP

Question 14

cellular respiration is what kind of reaction?

Answer 14

Exergonic reaction

Question 15

what is an exergonic reaction?

Answer 15

releases energy
glucose (that was produced in photosynthesis) is being broken down.
goes from glucose to ATP
ATP is needed for all energy

Question 16

parts of the cellular respiration formula

Answer 16

oxidation
reduction

Question 17

oxidation

Answer 17

lost the hydrogens to form CO2

Question 18

reduction

Answer 18

gain the hydrogens to form H2O

Question 19

three stages of cellular respiration

the three stages

Answer 19

stage one: glycolysis
stage two a&b: Pyruvate oxidation and citric acid cycle
stage three: oxidation phosphorylation

Question 20

stage one: glycolysis

location and function

Answer 20

location: cytoplasm/cytosol (jelly-like substance)
function: taking glucose (C6H12O6) and breaking it down to pyruvate (three carbon molecule)

starting with glucose and ending with pyruvate

Question 21

stage two a: pyruvate oxidation

location and function

Answer 21

location: mitochondria
function: start with pyruvate (three carbon molecule)
breaks the pyruvate down to CO2

Question 22

stage two b: citirc acid cycle

location and function

Answer 22

location: mitochondria
function: start with pyruvate is being broken down into Acetyl CoA (co-enzyme)
carbon is being kicked out and CoA comes in which makes 2 Carbons w/ CoA and still forms CO2

Question 23

stage 3: oxidation phosphorylation

location and function

Answer 23

location: mitochondria
function: NADH and FADH2: electron carriers that come from adding or removing Hydrogens
oxygen is reduced to Water
“electron transport chain and chemiosmosis”

Question 24

ATP from cellular respiration in stage one: glycolysis

Answer 24

two ATP’s

Question 25

ATP from cellular respiration in stage two: Pyruvate oxidation and citric acid cycle

Answer 25

two ATP’s

Question 26

ATP from cellular respiration in stage three: oxidation phosphorylation

Answer 26

28 ATP’s

Question 27

total number of ATP’s in cellular respiration

Answer 27

32 ATP’s

Question 28

fermentation: anaerobic harvesting of energy

does not require what?

Answer 28

does not require oxygen

Question 29

two types of fermentation

Answer 29

lactic acid
alcohol

Question 30

lactic acid fermentation

Answer 30

goes from pyruvate to lactose

Question 31

alcohol fermentation

Answer 31

goes from pyruvate to ethanol
