Bio 1b
| Question | Answer |
|---|---|
| Why can't lactose intolerant people drink milk? | they can't digest it (can't break up the glucose and galactose) because they lack the enzyme lactase |
| Activation Energy | The energy that must be overcome in order for a chemical reaction to occur. |
| Substrate | a molecule which binds to a specific enzyme |
| Denaturation | process of protein unfolding leading to the protein losing its function |
| Enzyme | Protein that increases the rate of chemical reactions |
| Why are enzymes called catalysts? | They facilitate a reaction |
| What macromolecule do enzymes belong to? | Proteins |
| What are enzymes sensitive to? | pH, temperature, ionic conditions, alcohol |
| What does an enzyme do to the activation energy of a reaction? | It lowers it by offering an alternative pathway |
| T/F in an endothermic reaction the energy is lower at the end | False, its absorbing energy so higher at the end |
| Photosynthesis is an _____thermic reaction | endo |
| Cellular respiration is an _____thermic reaction | exo |
| What does the enzyme DNA polymerase do? | makes a DNA polymer by adding nucleotides to the template strand |
| What does the enzyme RNA polymerase do? | makes a RNA polymer by adding nucleotides to the template strand |
| What does the enzyme helicase do? | It unwinds the DNA strands before replication and transcription |
| What does the enzyme exonuclease do? | It checks for mistakes made by polymerases and removes them |
| what doe the suffix -ase hint about the function of a molecule | that it is an enzyme |
