photosynthesis and cellular respiration

cellular respiration equation

C6H12 + 6O2→6CO2 + 6H2O + 36 ATP

cellular respiration step 1

glycolysis

cellular respiration step 2

the krebs cycle

cellular respiration step 3

electron transport chain

atmosphere

layer of gases that surround the earth

cyanobacteria

put oxygen into the atmosphere, photosytnthesis occurred

photosynthesis

process by which green plants and some other organisms use sunlight to make foods from carbon dioxide and water

takes CO2 from atmosphere

earth doesnt over heat

chloroplast

organelle where photosynthesis takes place, has ribosomes and DNA

grana

sack like membranes

stomata

leaf structure that allows for gas exchange

guard cells

make up stomata

CO2, O2

gases that move in and out of stomata

carbon

usable form of cellular energy that plants use

carbohydrates

what plants store carbon as

xylem

hollow tube within plant to transport water through plant

Epidermus cells

produce waxy coating on leaf which seals up leaf so the only way in and out is through the stomata

light reactions, calvin cycle

2 stages of photosynthesis

Electron carrier molecules

arranged in electron transport chains that produce ATP and NADPH, which temporarily store chemical energy

photosynthesis equation

CO2 + H2O → C6H12 + O2

- sunlight

energy source used in the light dependant reaction

- cytoplasm

where light dependant reaction takes place

- CO2, H2O

inputs of the light dependant reaction

- O2, C6H12O6

outputs of the light dependant reaction

- chlorophyll

molecule that absorbs light energy in chloroplasts

- light energy

excites electron within chloroplast

- atp, nadph

high energy molecules made in the light reaction, to be later used in the calvin cycle

- thykaloid membrane

location of the electron transport chain in light dependant reaction

photosystem ll

splits water, making oxygen and H+

- oxygen

output of photosystem ll, waste product of photosynthesis

photosystem l

makes nadph to be sent to dark reactions

- nadph

output of photosystem l

light dependant

uses atp and nadh to fix CO2 into glucose, makes ga3p as product

- nadp, adp

low energy molecules sent back to the light dependant reactions

- stroma

part of the choloplast where calvin cycle takes pace

- glucose

output of photosynthesis

- Calvin cycle

combines carbon from carbon dioxide in the air and uses the chemical energy in ATP and NADPH to make glucose
