photosynthesis + respiration + ATP + organic cycle

photo synthesis equation

6CO_2 + 6H_2O + energy —> C_6H_12O_6 + 6O_2

photosynthesis steps and where they occur

light reaction (thylakoid) —> dark reaction (stroma)

thykaloid

disc containing chlorophyll to absorb sunlight

geranium

stack of thykaloids

stroma

like cytoplasm (in chloroplast)

what organisms photosynthesize?

plants, algae, and some bacteria

what organisms use cellular respiration?

all living organisms

where does respiration occur in prokaryotes vs. eukaryotes

prokaryotes: cytoplasm, eukaryotes: mitochondria

respiration chemical equation

6O_2 + C_6H_12O_6 —> 6H_2O + 6CO_2 + ATP

aerobic respiration steps and where they occur

glycolysis (cytoplasm) —> aerobic respiration (mitochondria) —> Krebs cycle (matrix) —> electron transport chain (inner membrane)

anaerobic respiration steps and where they occur

glycolysis (cytoplasm) —> alcoholic or lactic acid fermentation (cytoplasm)

products of fermentation

alcoholic fermentation: ethanol and CO_2, lactic acid fermentation: lactic acid and CO_2

anaerobic vs. aerobic respiration ATP production

anaerobic: 2, aerobic: 38

ATP name

adenosine triphosphate

three parts of ATP

adenine, ribose sugar, 3 phosphate groups

where is energy in ATP stored

bond between 2nd and 3rd molecule

carbon cycle is powered by these two main processes

respiration and photosynthesis
