1
Q

how do we generate energy from fats

A

they are broke down into fatty acids and glycerol
glycerol is used as G3P and enters into cycle

Q

how is energy generated from proteins

A

broken down into amino acids
goes into pyruvate, acetyl coa, and krebs cycle
produces NH3 as waste, which we pee out

Q

where do the hydrogens come from?

A

from H2O

17
Q

2 major steps in photosynthesis

A

light reactions
calvin cycle

18
Q

how are photosynthesis and cr opposites

A

opposite products and reactants

19
Q

light reaction processes

A

harvests electrons from H2O and uses solar power to make ATP and NADPH

20
Q

The ATP and NADPH from light reactions are used in the calvin cycle by

A

using CO2, ATP, and NADPH to produce sugar then cycled back in as ADP and NADP+

21
Q

the photosystem structure function

A

captures the light
made up of proteins and chlorophyll
light hitting chlorophyll stimulates electrons which ends up at primary electron acceptor
the electrons are replaced from H2O, releasing O2 and H

22
Q

how does chlorophyll get excited

A

light hits pigment molecule, excites electron
these get absorbed or released by photons, which can decrease or increase energy

23
Q

how does light work

A

excited electrons fall back, releasing energy and shooting off a photon

24
Q

why are plants green

A

cholorphyll absorbs visible light waves except for green, which it reflects

25
Q

why are photosystems 1 and 2 linked

A

to make ATP and NADPH

26
Q

where does the calvin cycle occur

A

occurs in the stoma

27
Q

phase one of calvin cycle is called

A

carbon fixation

28
Q

enzyme present in phase one

A

rubisco (most abundant enzyme on earth)

29
Q

rubisco function

A

makes a 5C molecule into a 6C molecule

30
Q

what is used in phase one

A

ATP and NADPH from light reactions

31
Q

phase 2 of calvin cycle is called

A

reduction

32
Q

process of phase 2

A

g3P is made and used to make glucose
