Q

when there are lots of sugars pumped into a cell water potential (increases or decreases) and it becomes more (positive or negative)

Q

where does krebs and electron transport chain occur

A

in mitochondira

17
Q

input of glycolysis

A

glucose

18
Q

outcome of glycolysis

A

pyruvic acid and a little bit of ATP and NADH. You make 4 but use up 2 ATP

19
Q

another name for the krebs cycle is

A

the citric acid cycle

20
Q

what breaks down to form carbon dioxide

A

glucose

21
Q

name the 3 steps of respiration

A
  1. glycolysis
  2. krebs
  3. electron transport chain
22
Q

electron transport chain creates gradient of what

A

protons

23
Q

where does water come from in respiration

A

the electron from NADH to attach to O2 = H2O

24
Q

what is the total net yield of ATP

A

36 ATP

25
Q

if 6 carbon go into respiration, do 6 come out

A

no- plant needs to grow and it uses carbon for this

26
Q

respiration not only creates energy but helps support

A

maintenance, growth , nutrient uptake

27
Q
A
