Photosynthests and Cellular Respiration

TermDefinition
ATP is one of the most important compounds that cells use to store and release energy. phosphate groups added to ADP
Photosynthesis A process in which light energy, water and carbon dioxide are used to create glucose for energy.
Autotroph uses energy from the sun to make their own food
Heterotroph obtain food by eating other living things
chlorophyll most important photosynthesis pigment - it absorbs light energy
pigment substance that adds color
chloroplast found in cells of leaves , where photosynthesis takes place
Thylakoid disk shaped structures in the chloroplasts
Stroma space outside the thylakoid - fluid filled
Light dependent reactions light is absorbed by pigment - occurs in thylakoid
Light independent reactions trapped energy from the sun is used to make chemical energy called sugar - occurs in stroma
ADP two phosphate groups instead of three.
aerobic oxygen needed
cellular respiration a series of metabolic processes in which energy found in carbohydrates is transferred to ATP
anaerobic no oxygen needed
mitochondria organelle where energy is released
Cristae inner lining of mitochondria - makes 32 ATP
matrix a material in which something develops such as an organelle
Glycolysis break down glucose into 2 pyruvate molecules - 2 ATP
Kreb's Cycle citric acid cycle- occurs in mitochordria - pyruvate molecule is broken down into carbon dioxide makes 2 ATP
Electron Transport Chain oxygen is released to make lots of ATP
Pyruvic Acid a yellowish organic acid which occurs as an intermediate in many metabolic processes, especially glycolysis.
Fermentation Alcoholic - sugar is converted into cellular energy - yeast Lactic acid - occurs in muscle cells - sore muscles
