| photosynthesis | process in which light energy is converted to energy in sugars |
| respiration | process in which energy stored in food is converted to ATP |
| mitochonrion | organelle in which respiration occurs |
| chloroplast | organelle in which photosynthesis takes place |
| stoma / stomata | pores in the undersides of leaves that allow for gas exchange |
| guard cells | the pair of cells that make up a stomata |
| enzyme | an organic catalyst; controls the rate of chemical reactions |
| pH | a measure of how acid or base a solution is |
| neutral | not acid or basic; a solution around pH 7 |
| fermentation | anaerobic respiration; occurs in the absence of oxygen |
| lactic acid fermentation | occurs in muscles cells when oxygen is depleted |
| factos that can affect enzyme activity | temperature, pH, concentration |
| ATP | a molecule that contains stored energy |
| ADP | a molecule that is converted to ATP with the addition of a P group and energy |
| products of photosynthesis | glucose and oxygen |
| products of respiration | carbon dioxide, water, and ATP (energy) |
| synthesis | assembly of large molecules form smaller ones;requires energy |
| substrate | the molecule that an enzyme attaches to |
| autotrophic nutrition | obtaining food by producing it by photosynthesis or chemosynthesis |
| chlorophyll | green pigment that allows photosynthesis |
