Photosynthesis
Cellular respiration
How we get energy to do things
ALl organisms carry out cellular respiration in their cells
Heterotrophs eat other organisms to get their energy (animals)
Autotrophs: gets their energy from making it themselves (plants)
Photosynthesis
Over view
6CO2 + 6H2O → C6H12O6 + 6O2
The goal is to make sugar (glucose, starch)
Anabolic reaction (endergonic)
require energy to use
Energy comes from the sun
energy goes into chemical energy (into the bonds)
More details
Takes place in chloroplasts (organelle in plant cells)
Consists of light dependent reactions and light-independent reactions (
referred to light and dark reactions)
Light-dependent goal: to capture and bind energy
Takes kinetic (light) energy and makes it into chemical energy (potential) (
NADPH and ATP)
Energy used to drive Calvin cycle (dark reactions)
Light independent goal: Build 3 carbon molecules (carbon fixation)
Photosynthesis 1
, Where do things come from?
Energy – from the sun
H2O – from the roots
CO2– from the air
What comes out of it? Sugar molecules to be used as
Glucose – energy
Starch – energy storage
Cellulose – fibers (biomass)
O2:Released in the air
used in aerobic metabolic processes
Most Details
FLuid inside chloroplast: Stroma
Thylakoid: stack of membranes (looks like pancakes) makes up the granum
Light-dependent reactions: Electron Transport chain
Occurs across the thylakoid
