Q

What causes homeostasis to maintain balance

A

Organisms must respond to internal and external changes to maintain balance

Ex: homeostasis with body temp.
Human body temp. Stays at 98.6 if it changes you get sick

Q

What does aerobic respiration require

A

Free oxygen

17
Q

What happens to glucose in aerobic respiration

A

Completely oxidizes; loses electrons and breaks down

18
Q

Where is energy removed from in aerobic respiration?

A

Glucose

19
Q

When does aerobic respiration occur?

A

In almost all eukaryotic cells

20
Q

What process doesn’t need oxygen? How many glucose are made ?

A

Anaerobic respiration. 2 glucose

21
Q

What are the three main steps of respiration?

A

Glycolysis
Kreb’s
Electron transport chain

22
Q

Does glycolysis require oxygen? Where is it made and how many glucose

A

Doesn’t need oxygen
Occurs in the cytoplasm
And only 2 glucose made

23
Q

What does glycolysis break in half ? And at what temp does t happen

A

Breaks in half sugar and happens at low temp. Enzymes help break it down

24
Q

Where does Kreb’s cycle and ETC occur and what does it break down

A

Occurs in he mitochondria of the cell and breaks down the rest of glucose

25
Q

What are the three main steps in aerobic respiration

A

Glycolysis
Kreb’s
Electron transport chain

26
Q

Where does anaerobic respiration take place and does it need oxygen

A

In he cytoplasm of the cell and no oxygen

27
Q

Where does lactic acid formation occur

A

In bacteria and fatigued muscle cells (cytoplasm)

28
Q

Where does alcoholic fermentation occur

A

The cytoplasm

Occurs in yeast
