18
Q

What is activation energy

A

the amount of energy needed for a chemical reaction to start

19
Q

What is denaturation

A

an enzymes’ active site being deformed/misshaped so it cannot do its job (since they have such specific shapes)

20
Q

Catalysts

A

substances that speed up reactions without being permanently altered

21
Q

proteins that speed up biochemical reactions by lowering activation energy

A

enzymes

22
Q

name five ways to alter reaction rates

A

-pH
-temperature
-substrate concentration
-catalysts
-competitive inhibitors

23
Q

What is the purpose of an enzyme?

A

To speed up chemical and metabolistic reactions

24
Q

Where does photosynthesis take place?

A

Chloroplasts in plant cells

25
Q

What is the equation for photosynthesis in words?

A

carbon dioxide+water —-> glucose+oxygen

26
Q

What is the purpose of photosynthesis?

A

to convert sunlight, water, and carbon dioxide into chemical energy stored in glucose (to allow the plant to make its own food)

27
Q

Where do light independent reactions take place?

A

stroma

28
Q

Where do light dependent reactions take place?

A

grana

29
Q

What’s the order of photosynthesis?

A

light dependent then light independent

30
Q

what’s the equation of cellular respiration in words

A

glucose+oxygen —–> carbon dioxide+water+energy

31
Q

Where is ATP released?

A

Grana; light dependent reactions

32
Q

Where is NADPH released?

A

Grana; light dependent reactions

33
Q

Where is NADP+ released?

A

Stroma; light independent reactions

34
Q

Where is ADP released?

A

Stroma; light independent reactions

35
Q

What molecules are not charged enough so they’re sent back to the grana?

A

NADP and ADP

36
Q

What molecules are like the battery in light in/dependent reactions?

A

ATP and NADPH

37
Q

Where does cellular respiration take place?

A

mitochondria

38
Q

What is the order of photosynthesis

Where does the Krebs Cycle take place?

A

Mitochondrial Matrix

41
Q

Where does ETC take place?

A

Inner membrane of the mitochondria?

42
Q

Anaerobic respiration:

A

no oxygen (fermentation)

43
Q

Aerobic respiration:

A

oxygen present (Krebs and ETC)

44
Q
