Pre-Class Notes, Oct 1
| Question | Answer |
|---|---|
| What is the ratio typically between carbon, hydrogen, and oxygen in a carbohydrate | 1 to 2 to 1 |
| What are monosaccharides | simple sugars |
| What is a disaccharide | when 2 monosaccharides undergo dehydration synthesis |
| What is a glycosidic bond | covalent bond between carbon and another molecule, hydroxyl group of one monosaccharide combines with another, water leaves |
| What is glycogen | storage form of glucose |
| What is cellulose | comprise's plant's cell wall |
| What is ATP | powers the majority of energy, made of adenosine and 3 phosphate groups |
| What is a phosphoanhydride bond | phosphate bonds in ATP that are high-energy because products are much lower free-energy than reactants |
| What is energy coupling | coupling ATP hydrolysis with more endergonic reactions to make everything exergonic |
| What is the structure of ATP | alpha, beta, and gamma phosphate groups, ribose, and adenosine backbone |
| What is the function of enzymes | reduce activation energy required to reach transition state |
| What is induced fit | When enzyme and substrate come together, there is a mild shift in enzyme structure that is ideal binding, enzyme returns back to original shape after |
| What is competitive inhibition | inhibitor molecule competes with substrate for active site binding |
| What is noncompetitive inhibition | inhibitor molecule binds to enzyme in a location called allosteric site, prevents substrate from attaching to active site in the same enzyme |
