Q

what is the mitochondria?

A

it is an organelle which is the site of aerobic respiration and ATP production in cells

17
Q

what is respiration common to?

A

it is common to all living cells

18
Q

what does respiration provide?

A

respiration provides usable energy to allow organisms to move, grow, stay warm, and carry out essential chemical reactions.

19
Q

what is energy used for in cells?

A

-transmission of nerve impulses

20
Q

what requires energy to be formed?

A

ATP

21
Q

what is ATP used as?

A

a source of energy in cells

22
Q

what is ATP broken down into?

A

ADP + Pi

23
Q

what is the word equation for respiration?

A

glucose + oxygen —-> Water + CO2 + Energy

24
Q

when does fermentation occur?

A

when no oxygen is present or their is a lack of oxygen

25
Q

what is the word equation for fermentation in yeast cells?

A

Glucose —-> x2 Pyruvate <——-> CO2 + Ethanol (and in the process 2ATP are produced)

26
Q

what does fermentation in plant and yeast cells carry out?

A

Glycolysis

27
Q

what is no longer produced after the pyruvate has been broken down by fermentation?

A

energy

28
Q

what is the ‘fermentation pathway’?

A

it is the name pf the pathway that takes place in animal, plant, and fungal cells in the absence of oxygen

29
Q

Do muscle cells have lots of mitochondria?

A

Yes because they need to produce energy

30
Q

What is respiration?

A

A series of enzyme controlled reactiosn

31
Q

What is the word equation for aerobic respiration?

A

Glucose + oxygen ———> oxygen + Water + Energy

32
Q

What is glycolysis?

A

When glucose is broken down into energy

33
Q

What are enzymes?

A

The are biological catalysts which increase the rate of a chemical reaction

34
Q

Why do humans have an optimum of 37 degrees Celsius?

A

Because they don’t, many bodily functions will begin to break down
