glycolysis > link reaction > krebs cycle > electron transport chain

1 of 15

Methylene blue is a chemical that models how co-enzymes work by 1............ hydrogen ions, 2.......... it changing the colour 3...............

1accepting 2 reducing it 3from blue to colourless

2 of 15

Where does glycolysis take place?

in the cytoplasm

3 of 15

Where does the link reaction & krebs cycle take place?

in the mitchrondial matrix

4 of 15

Where does the electron transport chain take place?

in the mitochrondial cristae

5 of 15

At the start of glycolysis, glucose is activated by ...................

phosphorylation (bonded to 2 phosphate molecules)

6 of 15

What are the end products of glycolysis?

pyruvate, ATP, NADPH

7 of 15

The reaction that happens in the Link reaction is....

Pyruvate + coenzyme A + NAD -> CO2 + Acetyl coenzyme A + reduced NAD

8 of 15

What is the yield of Carbon dioxide from aerobic respiration for each molecule of glucose?

6 CO2 molecules

9 of 15

In the electron transport chain, energy from electrons is used to....

pump H+ from the matrix into the inner membrane space

10 of 15

In the ETC there are a series of electron carriers. As electrons are passed along them the electrons....

lose energy

11 of 15

At the end of the ETC, the protons are finally accepted by oxygen to produce water. This makes oxygen the...

terminal electron acceptor

12 of 15

During anaerobic respiration, pyruvate is used to make....

ethanol and CO2 in plants and Lactate in animals

13 of 15

Lactate produced by anaerobic respiration can be...

converted into glycogen or oxidised for aerobic respiration

14 of 15

What is the equipment for measuring the rate of respiration called and what is it based on?

Respirometer, based on measuring gas volume
