Q

Why do plants need stomata for photosynthesis

A

Carbon dioxide goes in through the stomata and without it photosynthesis wouldn’t occur

Q

Where does the Calvin cycle take place

A

Stroma of the chloroplast

17
Q

What are the reactants and products of the Calvin cycle

A

Co2, ATP, NADPH —> glucose, NADP+, ADP

18
Q

What factors affect the rate of photosynthesis

A

Light intensity
Water
Temperature
Carbon dioxide

19
Q

How is the suns energy used in photosynthesis

A

Breaks water bonds

20
Q

The energy in high energy electrons is used for what during electron transport chain

A

They move down the electron transport chain and the energy moves H+ ions across the membrane

21
Q

Where do the starting materials of cellular respiration originate

A

Products of photosynthesis

22
Q

What is the difference between aerobic and anaerobic processes

A

Aerobic: a process with oxygen
36-38 ATP/ takes longer

Anaerobic: process without oxygen
Lactic acid
2 ATP/faster

23
Q

How does the number of ATP compare in aerobic vs anaerobic conditions

A

Aerobic —> 36-38

Anaerobic —> 2

24
Q

What is the chemical equation that represents cellular respiration

A

C6 H12 O6 + 6o2 —> 6co2 + 6h20 + energy Krebs
Cycle

25
Q

What are the stages involved in aerobic respiration

A

Glycolysis
Krebs cycle
Electron transport chain

26
Q

Name the reactants and products for glycolysis

A

Glucose —> ATP, NADPH, pyruvic acid

27
Q

Name the two electron carriers I cellular respiration

A

NADH

FADH2

28
Q

Where are the electrons dropped off

A

Electron transport chain

29
Q

Why is fermentation necessary in cells

A

It is necessary because when cells are losing oxygen, they need to be able to release energy still and fermentation allows this

30
Q

When oxygen is present, what is glycolysis followed by

A

Krebs cycle

31
Q

What does Krebs cycle begin with and what does it produce

A

Acetyl CoA —> carbon dioxide, high energy electrons, carried by NADH + ATP

32
Q

Where does the ETC and Krebs cycle occur in eukaryotic cells

A

Mitochondria

33
Q

How many ATP total are produced with glycolysis, Krebs, ETC and the entire process out together

A

36-38

34
Q

Why do muscles burn after strenuous exercise

A

Our body needs ATP and when oxygen is used, we need fermentation(anaerobic respiration) to take ATP fast which produces lactic acid and it burns

35
Q

How are photosynthesis and cellular respiration almost opposite processes

A

Photosynthesis makes what cellular respiration uses and cellular respiration makes what photosynthesis uses

(Sunlight goes in)
PHOTOSYNTHESIS (out) glucose and oxygen

CELL RESP(out) h2o ad Co2

36
Q

In what type of cells does cellular respiration occur

A
