Bioenergetics of Sports Performance

Question 1

Glycolysis

Answer 1

Phosphofructokinase
Sugar food can help replenish glycogen
Glucose > ADP > ATP > Pyruvate

Question 2

Beta Oxidation

Answer 2

Fatty acyl CoA is broken down to generate acetyl CoAs, which can then enter the TCA cycle, as well as FADH2 and NADH.

b-Oxidised of fatty acids

Question 3

What are the Transport of fatty acid and what its function

Answer 3

Albumin + FA binds to fatty acid binding proteins

Allows for the transportation of FA across the plasma membrane into the cytoplasm.

Question 4

Carbohydrate metabolism: how does it function and

Answer 4

CHO metabolism can be fueled by muscle glycogen and plasma glucose

• Higher levels of glycogen will be able to sustain exercise for longer periods of time

Question 5

Latic Acid Production What is it function

Answer 5

Muscle fatigue

Question 6

Lactate: function

Answer 6

(such as the heart or slow twitch muscle fibres) for oxidation, or through the process of gluconeogenesis can be converted to glucose (or stored as glycogen) in the liver.

Question 7

Lactate: two essentials enegery systems

Answer 7

Glycoysis and aerobic

Question 8

what does Lipid Metabolism

Answer 8

triglycerides in adipose tissue, liver and skeletal muscle and are an essential energy substrate, especially during

Question 9

Fatty acids and glycerol in circulation: what does it remove (3)

Answer 9

1) Blood flow through adipocyte
2) Number of albumin molecule
3) # of free binding sites on albumin

Question 10

function of Beta Oxidation

Answer 10

Taking the free fatty acids and splitting them making into 2 carbon Acetyl COA molecules which contrbute to the kreb cycle
