33 A) Starch is made up of α-glucose molecules. These molecules in starch are arranged in a helical structure. This makes starch more compact and suitable for storage rather than as a support function.
As for cellulose, they contain β-glucose molecules. Every alternate molecule in a chain of molecules is rotated 180degrees. This enables the formation of hydrogen bonding between neighboring chains of molecules. Put all the chains together and cellulose is formed. With the chains tightly bonded(by hydrogen bonding), cellulose have a high tensile strength,thus it is a strong structural material.
B.)It is the cell wall of plants. They don't have bones, so they need some form of rigidity.
34. A drug interaction is a situation in which a substance (usually another drug) affects the activity of a drug when both are administered together. This action can be synergistic (when the drug's effect is increased) or antagonistic (when the drug's effect is decreased) or a new effect can be produced that neither produces on its own. Typically, interactions between drugs come to mind (drug-drug interaction). However, interactions may also exist between drugs and foods (drug-food interactions), as well as drugs and medicinal plants or herbs (drug-plant interactions). People taking antidepressant drugs such as monoamine oxidase inhibitors should not take food containing tyramine as hypertensive crisis may occur (an example of a drug-food interaction). These interactions may occur out of accidental misuse or due to lack of knowledge about the active ingredients involved in the relevant substances
