Homeostasis Maintaining a stable internal environment Photosynthesis Converting light energy (sunlight) into chemical energy (glucose) Cellular Respiration Converting glucose into (energy) ATP ATP High energy molecules made from glucose in the mitochondria. Proteins Makes up enzymes and many cell parts Lipids (fats and oils) Acts as a food reserve molecule. Releases energy slowly. DNA Carries hereditary information glucose A simple sugar made during photosynthesis. It is a carbohydrate. carbohydrates Acts as a food reserve molecule. Releases energy quickly. enzymes Special proteins that control the rate of chemical reactions. biochemical processes Chemical processes that occur in living things. chloroplasts organelle that carries out photosynthesis in green plants and algae mitochondria organelle that carries out cellular respiration gas exchange Obtaining oxygen from the environment and and releasing carbon dioxide. synthesis To combine chemically. catalyst Any substance affecting the rate of a chemical reaction optimum ideal or most favorable conditions dynamic equilibrium constant small corrections that normally help keep homeostasis stimuli changes in the environment allergy a rapid immune response to normally harmless environmental substances guard cells specialized cells that surround pores on the surface of a leaf. stoma pores in a leaf pathogen disease causing organism antibodies proteins that either attack foreign invaders or mark them for killing
