cellular respiration

Question 1

what is the first step

Answer 1

glycolysis

Question 2

where does the first step happen in

Answer 2

the cytoplasm

Question 3

what does the fist stage from and how

Answer 3

glycolysis - it froms pyruvate from when gloucose breaks down but since its breaking it needs to use engery

2 adp to 2 atp that turn to 4 atp

then forms 2 NADH from NAD

Question 4

what moves from first stage glyolysis to pre-krebs

Answer 4

its the 2 pryuvate that moves into it

Question 5

where is pre-krebs take place

Answer 5

in the mitocondria

Question 6

does glycolysis need o2

Answer 6

nope

Question 7

does pre-krebs and krebs need o2

Answer 7

yes

Question 8

one the c6 and pryuvate is in pre-krebs what happens to the c6

Answer 8

2 of the atoms turn and let of waste as co2

Question 9

what happens to the other 4 atoms of c6 in pre-krebs

Answer 9

theyre fromed into 2 acetyle coa and in process let of NADH

Question 10

what moves from pre-krebs to krebs cycle

Answer 10

the 2 acetyle coa moves into krebs

Question 11

what does the 2 acetyle coa join to in the krebs cycle and what does it realease

Answer 11

it joins the 4 carbon (oxalocetate) then the 2 acetyle coa relase co2 and nad t nadh

Question 12

after the 2 acetyle coa releases its first things what does it produce

Answer 12

after giving of waste co2 and nad to nadh since its realeaseing it uses energy so

makes atp then makes

another nad to nadh

then fad to fadh

Question 13

overall how many things are made in the krebs cycle after 2 spins

Answer 13

6 nadh
2 fadh
2 atp
4 co2

Question 14

what does nadh do

Answer 14

like delivery truck carries high energy in cells and grabs electrons / protons to make it energy then goes over and over

(like setting up the battery then to power cells)

Question 15

what does fadh2 do

Answer 15

its like helper in cells takes electrons to make energy help cells have energy

(nadh and fadh2 are bascially same thing in this course)

Question 16

how are nadh made in glycolisis

Answer 16

theyre made from when glucose breaks down (pyruvate)

then enzymes transfer electrons/ protons (H+) from gloucose to make nad into nadh

(nadh made from transfer of electron/proton)

Question 17

where does krebs take place

Answer 17

the matrix in mitochondria

Question 18

where does the ect take place

Answer 18

inner mitochondria inner layer mitochondria
