Are protons pumped when electrons are transferred to CoQ?
(Complex II:Succinate Dehydrogenase)

Back 13

No

Front 14

The lack of protons pumped in the electron transfer to CoQ results in and increase or decrease of ATP?

Back 14

Decrease

Front 15

(ATP Synthase)
The F1 portion of the ATP synthase consists of what and how many dimers?

Back 15

3 alpha/beta-dimers

Front 16

(ATP Synthase)
Do the operators (alpha/beta dimers) work in sync or independent?

Independent

Front 17

(ATP Synthase)
(ATP Synthase)
Influx of what causes the interaction of the Gamma subunit with the alpha/beta dimers to change?

Back 17

Proton influx

Front 18

(ATP Synthase)
(ATP Synthase)
The energy poduced from the proton flow causes a conformational change creating what?

Back 18

ATP

Front 19

(ATP Synthase)
What needs to happen to allow the release of ATP locked in the Beta portion of the dimer?

Back 19

Catalysis of the Gamma subunit

Front 20

Brown Adipose Tissue is found where on infants?

Back 20

Neck, back and kidneys

Front 21

What is contained within Brown Adipose Tissue that produces heat?

Back 21

Uncoupling protein called THERMOGENIN that uncouples mitochondria

Front 22

What activates Thermogenin?

Back 22

Norepinephrine release from cold chills or food intake

Front 23

What is a Symport and an example of one?

Back 23

Translocase which moves 2 ions in same direction across the membrane.
ie as Proton moves with a Pyruvate into the mitochondrial matrix there is no net change in charge

Front 24

What is a Antiport and an example of one?

Back 24

a charged molecule is exchanged for a different charged molecule
ie ATP-ADP Translocase where ATP in the mitochondrial matrix is exchanged for ADP

Front 25

What is a Uniport and an example of one?

Back 25

Only one molecule is transported
ie a Calcium channel which can allow Calcium to enter the mitochondria

Front 26

Transport across the inner mitochondrial membrane is executed by?

Back 26

Translocase

Front 27

What binds Hexokinase in the outer mitochondrial membrane?

Back 27

Voltage Dependent Anion Channels

Front 28

Is hexokinase a cytosolic protein?

Back 28

Yes

Front 29

The binding of hexokinase to Voltage Dependent Anion Channels on the outer membrane of the mitochondrial membrane permits what to happen?

Back 29

Hexokinase now has access to newly exported ATP

Front 30

Creatine Phosphate plays what role in energy buffering in the brain, skeletal muscles and heart?

Back 30

Contains high energy phosphate bonds. A net transfer of high energy phosphate from it to ADP to form ATP. As the ATP levels return to resting levels, creatine phosphate is regenerated.

Front 31

What form of energy is stored in the cardiac muscle?

Back 31

Creatine Phosphate

Front 32

Creatine Phosphate is used to generate more and where?

Back 32

ATP in the heart

Front 33

As heart rate increases, what happens to ATP?

Back 33

It is depleted

Front 34

In aerobic conditions, within few seconds of exercise, when ATP depletes, what takes over its production?

Back 34

Creatine Phosphate

Front 35

Creatine Phosphate plays what role in energy buffering in the brain, skeletal muscles and heart?

Back 35

Contains high energy phosphate bonds. A net transfer of high energy phosphate from it to ADP to form ATP. As the ATP levels return to resting levels, creatine phosphate is regenerated.

Front 36

What form of energy is stored in the cardiac muscle?

Back 36

Creatine Phosphate

Front 37

Creatine Phosphate is used to generate more and where?

Back 37

ATP in the heart

Front 38

As heart rate increases, what happens to ATP?

Back 38

It is depleted

Front 39

In aerobic conditions, within few seconds of exercise, when ATP depletes, what takes over its production?
