Vocab using root words
| Questions | Answer |
|---|---|
| Photosythesis | process by which autotrophs such as algae and plants, trap energy from sunlight with chlorophyll and use this energy to convert carbon dioxide and water into simple sugars |
| Chlorophyll | light absorbing pigment in plants and some protists that is required for photosynthesis; absorbs most wavelengths of ligh except for green |
| Photolysis | reaction taking place in the thylakoid membranes of a chloroplast during light-dependent reactions where two molecules of water are split to form oxygen, hydrogen ions, and electrons |
| Glycolisis | in cellular respiration, series of anaerobic chemcial reactions in the cytoplasm that breaks down glucose into pyruvic acid, forms a net profit of two ATP molecules |
| anaerobic | chemical reactions that do not require the presence of oxygen |
| aerobic | chemical reactions that require the presence of oxygen |
| triphosphate | Three phosphates |
| isomer | compounds with the same simple formula but different three-dimensional structures resulting in different physical and chemcial properties |
| polymer | large molecule formed when many smaller molecules bond together |
| enzyme | type of protein found in all living things that changes the rate of chemcial reactions |
| biomolecule | a large organic molecule found in living organisms; examples are carbohydrates lipids, proteins, and nucleic acids. |
| polysaccarides | many sugars |
| disaccaride | two sugars |
| monosaccaride | one sugar |
| cytoplasm | clear, gelatinous fluid in cells that is the site of numerous chemcial reactions; in eukaryotic cells, it suspends the cell's organelles |
| endoplasmic | within the plasma |
| vacuole | membrane-bound space in the cytoplasm of cells used for the temporary storage of materials (empty) |
| lysosome | organelles that contain digestive enzymes; digest excess or worn out organelles, food particles, and engulfed viruses or bacteria |
| cytoskeleton | cellular framework found within the cytoplasm composed of microtublules and microfilaments |
| mitochondrian | eukaryotic memrane-bound organelles that transform energy stored in food molecules; has a highly folded inner membrane that produces energy-storing molecules. |
| chloroplast | chlorophyll-containing organelles found in the cells of green plants and some protists; capture light energy and converted it to chemical energy. |
| phospholipid | lipids with an attached phosphate group; plasma membranes are composed of phospholipid bilayer with embedded proteins. |
