Q

Autotroph VS Heterotroph

A

Autotroph are knows as producers bc they are able to make their own food from raw materials and energy, heterotroph are consumers they consume producers or other consumers.

Q

Light dependent VS light independent

A

Light dependent create O2 from H2O, ATP, NADPH occurs in the thylakoid membrane of the chloroplast
Light independent create glucose using CO2 (the Calvin cycle) occurs in the stroma of the chloroplast

Q

What is the general purpose and product of photosynthesis 1?

A

Makes ATP, uses light energy to produce the high energy carriers ATP and NADPH shuttle electrons and photons

Q

What is the general purpose and products of photosynthesis 2

A

Moves electrons and hydrogen + (protons) across thylakoid membrane
Creates gradient that will later be used to make ATP

Q

Why is it necessary to have both photosystem 1 & 2

A

There is not enough energy to provided from a single photon to produce the energy carrying molecule needed like NADPH

16
Q

What happens in fixation

A

Ribulose Biphosphate reacts with CO2
PRODUCES 6 carbon compound sp
SPLITS in two -> 3-phosphoglycerate
RUBISCO (enzyme)
USES CO2

17
Q

What happens in reduction

A

ATP phosphorylates 3-phosphoglecerate
NADPH reduce it
Together these will PRODUCE glyceraldehyde 3-phosphate (G3P)

18
Q

What happens in Regeneration

A

Some G3P is used to regenerate RUBP

19
Q

What happens if O2 levels inside the plant cell climb in comparison to carbon dioxide levels ?

A

Photorespiration (reverse photosynthesis)
Oxygen out competes CO2 in Rubisco

20
Q

What structure and cells allow carbon dioxide into a plant cell

A

Stomata 2 guard cells create pore when CO2 level inside drops
