Entropy

Answer 6

Random energy
Can’t do work

Question 7

Gibbs free energy

Answer 7

Some energy is useful and can do work

Question 8

Glycolysis 1

Question 32

*reduce glucose to pyruvate and also produce ATP molecules.

Answer 32

gycolisis 2

Question 33

Glycolysis 2 summary

Answer 33

formation of ATP and NADH

Question 34

Metabolic rate

Answer 34

The amount of energy consumed by an organism in a given amount of time

Question 35

Basal metabolic rate

Answer 35

The minimum amount of energy needed to keep and organism alive. This is dependant on age growth and development

Question 36

Explain the correlation between age and Basal metabolic rate

Answer 36

As we age our basal metabolic rate decreases which in turn means our metabolism slows down. This can cause things like the freshman 15 in people around the age of 20.

Question 37

**Why does lactic acid fermentation occur?

Answer 37

Your cells cannot get enough oxygen through aerobic respiration so instead they use anaerobic respiration in the form of lactic acid fermentation to allow continuous production of ATP.

Question 38

What is the lactate threshold?

Answer 38

blood lactate concentration begins to increase sharply. Once reached a burning sensation is felt and exercise is limited.

Question 39

Why is 2 acetyl CoA 2NADH 2H+ 2CO2 not accurate

Answer 39

Nothing is 100% efficient Can't gaurentee it will produce that yeild

Question 40

Autotroph

Answer 40

An organism that makes its own food

Heterotroph

Answer 41

An organism that cannot make its own food.

Question 42

Electron Transport Chain Summary

Answer 42

Proteinscouple Electrons pass through from redox reactions Release Energy makes atp

Question 43

*Why does exercise improve metabolic rate

Answer 43

Muscles use calories More used to the burning sensation Increases Basel metabolic rate (relate to freshman 15)

Question 44

*Explain the process of a heart attack
