Cellular Respiration PT1

Question 1

What happens during cellular respiration

Answer 1

energy in fuel is converted into ATP

Question 2

what is glycolysis and where

Answer 2

located outside of mitochondria

Question 3

what happens after energy is invested

Answer 3

molecule splits in half, one half NAD+ picks up hydrogen atoms from carbon becoming NADH

Question 4

what happens during the final steps of glycolysis

Answer 4

ATP is produced, (one glucose= 2 ATP, produces pyruvic acid)

Question 5

byproduct of pyruvic acid

Answer 5

carbon dioxide ,

Question 6

pyruvic acid froms

Answer 6

NADH

Question 7

final steps of pyruvic acid

Answer 7

acetyl CoA

Question 8

first step of citric acid cycle

Answer 8

acetyl coA forms 4 carbon molecule,

Question 9

out come of 6 carbon molecule

Answer 9

release carbon dioxide

Question 10

what is oxidative phosphorylation process

Answer 10

energy carries go into electron transport chains. high hydrogen ion concentrations

Question 11

How do catabolic pathways produce energy

Answer 11

produces energy by oxidizing organic fules

Question 12

what happens in oxidation

Answer 12

Substance loses electrons

Question 13

whats happens in reduction

Answer 13

substance gains electron or reduction of oxygen atom

Question 14

what are redox reactions

Answer 14

chemical reactions that transfer electrons between reactant

Question 15

Difference between oxidized form and reduce form

Answer 15

oxidized- not yet carrying electrons for cell. reduce- carrying electrons for cell

Question 16

where do electrons from organic compounds go

Answer 16

NAD+ a coenzyme

Question 17

what does FAD+ do

Answer 17

carry electrons becoming FADH+2 during the tricarboxylic cycle

Question 18

how does NAD+ shuttle electrons

Answer 18

reducing agent+ NAD+->NADH (reduced)+R (Oxidized )

Question 19

what does the electron transport chain

Answer 19

passes elctrons in steps instead of one explosive reaction

Question 20

what is the energy investment phase in glycolysis

Answer 20

Glucoses goes in 2 ATP used (higher chemical reactivity )

Question 21

what is the energy pay off phase

Answer 21

4 ATP formed. 2NADH produces pyruvate. (Reversible, never reaches equilibrium )

Question 22

what is G3P

Answer 22

important end product of energy inveptment phase

Question 23

why is fermenation used

Answer 23

when oxygen is not present to regeneratue NAD+ NADH
