Biochemistry
Term | Definition |
---|---|
Carbohydrates | Large Organic molecule (ex starch) made up of small monosaccharides (simple sugars). Used for energy |
Lipids | Large Organic molecule made up of smaller fatty acids and glycerol. Used for stored energy, and cell membrane |
Proteins | Large Organic molecules made up of amino acids. Examples are enxymes, hormones, antibodies. |
Nucleic Acids | Large Organic molecules made up of nucleotides. Ex. DNA, RNA |
Organic Molecules | Contain Carbon, and Hydrogen |
Inorganic Molecules | DO NOT have both carbon and hydrogen |
Enzymes | Proteins that are catalysts: they speed up reactions. They split molecules apart or put them together |
Denature | When enzymes change shape due to different temperatures or pH |
Substrate | The molecule being put together or broken apart by the enzyme |
Diffusion | Movement of molecules from High to Low concentration. NO Energy needed. |
Active Transport | Movement of molecules from Low to High Concentration- requires ENERGY |
Osmosis | Movement of water across a membrane from High to Low Concentration |
Starch | Large carbohydrate- cant fit through cell membrane. Gets broken down into glucose |
Glucose | can fit through the membrane. |
Starch Indicator | Turns purple black when it comes into contact with starch |
Glucose Indicator | Turns orange when it comes into contact with glucose and heated |
