Organisms unicellular colonial multicellular

unicellular uni cellular one cell

tissue similar cells working together

organ group of tissues working together

cellular respiration the breakdown of an energy source by cells to obtain usable energy

Enzymes are catalysts. enzyme

catalyst substances which change other substances without being permanently changed themselves

Catalysts are tools.

Cellular Respiration aerobic aerobic cellular respiration oxygen

aerobic respiration the process by which cells use oxygen to obtain usable energy from an energy source

sugar + oxygen = carbon dioxide + water + energy

anaerobic cellular respiration the process by which cells obtain energy from an energy source without using oxygen

carbon dioxide energy sugar alcohol & lactic acid

alcoholic fermentation produces alcohol and carbon dioxide from glucose

Know ye not that a little leaven leaveneth the whole lump? Yeast leavening agent causes bread to rise I Corinthians 5:6 Know ye not that a little leaven leaveneth the whole lump?

Cellular Respiration anaerobic cellular respiration alcoholic fermentation lactic acid fermentation

lactic acid produced by bacteria that are present in certain foods

sugar  energy + lactic acid cellular respiration releases general type general type aerobic anaerobic sugar  energy + lactic acid lactic acid fermentation sugar + oxygen  energy + carbon dioxide + water aerobic respiration sugar  energy + alcohol + carbon dioxide alcoholic fermentation requires does not require examples energy oxygen alcoholic fermentation from from produces and sugar fat carbon dioxide lactic acid fermentation and water

photosynthesis the process that most producer organisms use to change light energy into chemical energy

photosynthesis the process that forms simple sugars from carbon dioxide and water, using light energy in the presence of chlorophyll

carbon dioxide + water + light energy sugar + oxygen photosynthesis

P hotosynthesis Requirements special pigments special organelles special enzymes

P hotosynthesis Requirements special pigments chlorophyll

chlorophyll the green pigment located in the chloroplasts of plant cells, green algae, and several green protists

P hotosynthesis Requirements special organelles chloroplasts

chloroplast

P hotosynthesis Requirements special enzymes

sunlight oxygen carbon dioxide chlorophyll sugar water

P hotosynthesis takes energy and converts it to sugar

cellular respiration photosynthesis energy sugar sugar energy

carbon dioxide + water + energy sugar + oxygen cellular respiration carbon dioxide + water + energy cellular respiration

carbon dioxide + water + light energy photosynthesis sugar + oxygen photosynthesis
