Definitions

Lactic Acid Cause of sore muscles
Alcoholic Fermentaion Used in Brewing, baking, and carbonating
Glycolysis First stage of cellular respiration
Electron Transport Chain Series of protiens embedded in a membrane that make energy
Cellular Respiration Total Reaction C6H12O6+ 6O2 to 6CO2+ 6H2O
ATP adenosine triphosphate
ATP high energy molecule used to do work in the cell
ATP releases energy when a phosphate is removed
ATP uses the energy from the breakdown of food to produce energy for cells
autotroph make their own food, usually through photosynthesis
ex: plants
heterotroph eat other organisms
ex: animal
light dependent reactions takes place in the thylakiod
light independent reactions aka Calvin Cycle
takes place in the stroma
chloroplast organelle in plant where photosynthesis occurs
reactants of photosynthesis carbon dioxide and water
products of photosynthesis oxygen and sugar (glucose)
mitochondria organelle where cellular respiration occurs
reactants of cellular respiration sugar (glucose) and oxygen
products of cellular respiration water and carbon dioxide
glycolysis first step of cellular respiration
occurs in the cytoplasm
anaerobic process (does not require oxygen)
breaks down glucose to make pyruvate and 2 ATP
Krebs Cycle occurs in the matrix of the mitochondria
releases carbon dioxide
Electron Transport Chain occurs in the membrane of the mitochondria (cristae)
produces water and lots of ATP
Lactic Acid Fermentation produces lactic acid
bacteria do this process
responsible for sore muscles and sour dairy products (yogurt, sour cream, buttermilk, cheese)
Alcoholic Fermentation produces carbon dioxide and alcohol
yeast do this process
responsible for brewing, carbonating, and baking (bread)
Fermentation anaerobic process (doesn't use oxygen) to break down sugars into ATP
only goes through glycolysis
produces 2 ATP
less efficient than cellular respiration
Total number of ATP made through cellular respiration 36
Total Reaction for Photosynthesis 6CO2+ 6H2O to C6H12O6+ 6O2
photosynthesis the process by which plants covert light energy into chemical energy (food)
chemosynthesis the process by which some autotrophs covert chemical energy to the the chemical energy in food
water molecule broken down during photosynthesis to release oxygen
