1
Q

glycolysis

A

happens in the cytoplasm
doesnt requitre oxygen
product is two 3Cpyruvate
uses two ATP makes 4 ATP and 2NADH

2
Q

substrate level phosphorylation

A

making ATP without an ETC.

ATP made by transferring a phosphate group from a phosphorylated intermediate to ADP

3
Q

outer mitochondrial membrane

A

separates the contents of the mitochondrion from the rest of the cell making a cellular compartment with ideal conditions for aerobic respiration

4
Q

intermembrane space

A

proteins are pumped into here by the ETC, this space is small and the concentrations builds up quickly

5
Q

cristae

A

projections of the inner membrane with increase the SA available for oxidative phosphorylation

6
Q

inner mitochondrial membrane

A

contains ETC and ATP synthase

7
Q

matrix

A

contains enzymes for the krebs cycle and the link reaction also contains mitochondria DNA

8
Q

oxidative phosphorylation

A

the formation of ATP from ADP,its dependant on electrons moving along the ETC and requires the presence of oxygen
occurs along the ETC which involves a series of membrane bond complexes

9
Q

Substrate level phosphorylation

A

making ATP, involving the transfer of a phosphate group from a short lived highly reactive intermediate like creatine phosphate

10
Q

Obigate anerobes

A

Cant survive in the presence of oxygen

Almost all are prokaryotes eg Clostridium that causes food poisoning

11
Q

Facultative anerobes

A

Make ATP by aerobic respiration if oxygen present

Can switch to anaerobic when there’s no oxygen, like yeast

12
Q

Obligate aerobes

A

Can only make ATP in the presence of oxygen.
However individual cells within the mammal eg their muscle cells, can be described as facultative anerobes
Cuz they can add to their ATp byusing anaerobic as well as aerobic when o2 con low.
Only for short period of timer
Makes compounds that have to be broken down where o2 present again. Whole organism is obligate though

13
Q

Fermentation

A

A form of anerobicnrespiration

Complex organic compounds broken into simple inorganic compounds without the use of oxygen or the etc
