BSC1010-Metabolism
PBSCBSC- An Introduction to Metabolism
| Question | Answer |
|---|---|
| The addition of a phosphate to any molecule or substrate. | Phosphorylation |
| In a reversible reaction, if there is more product, which way will the reaction proceed? | Toward the production of Reactant. |
| This law states that the total amount of the energy in the universe remains constant. | First Law of Thermodynamics |
| Metabolic reactions whereby the products have more energy than the reactants. | Endergonic |
| Which has LESS potential energy, ADP or ATP? | ADP |
| What does ATP stand for? | Adenosine Tri Phosphate |
| What is the name of the region of an enzyme which binds the substrate? | Active Site |
| This law states that all ordered systems proceed toward increasing randomness over time. | Second Law of Thermodynamics |
| This is defined as the capacity to do work. | Energy |
| What are the building blocks of enzymes? | Amino Acids |
| The gain of electrons is called _______. | Reduction |
| The term for changing the shape of a protein either by high heat or a change in pH. | Denaturation |
| The loss of electrons is known as _______. | Oxidation |
| The name of the substrate when it is at the top of the energy hill and it is said to be "activated". | Transition State |
| The type of allosteric control whereby product feeds back allosterically to turn off the enzyme. | Feedback Inhibition |
| The shorthand term for when reduction and oxidation reactions are coupled. | Redox Reactions |
| This is defined as energy use and transfer. | Metabolism |
| Metabolic reactions whereby the products have less energy than the reactants. | Exergonic |
| The type of enzymatic control whereby the reaction is controlled by the binding of a molecule to a seconedary binding site. (other than that of the active site) | Allosteric Control |
| A measurement of disorder or randomness. | Entropy |
| The type of enzymatic control whereby a molecule similar to the substrate blocks the active site by binding to it. | Competitive Inhibition |
| What is the name of the model which specifies that the enzyme's active site changes to fit the shape of the substrate? | Induced Fit Model of Enzymes & Substrates |
| Enzymes speed up the rate of reactions by lowering the _______. | The Energy of Activation |
