Answer:
a) true
b) false
c) true
d) false
e) false
Explanation:
hi im taking ap biology and it's not my best subject but here r my reasonings:
a) inhibitors decrease the rate of reactions in general, so i would assume that increasing the number of inhibitors would decrease the overall rate or reaction
b) it's false bc allosteric inhibitors bind to a place on the enzyme other than the active site. u can see on the figures that the blue-green allosteric inhibitor is in a place other than the active site at the top
c) because allosteric inhibitors bind to a different place on the enzyme, this often results in an formational change in the enzyme. bc of this change in shape of the enzyme, this can rly prevent the substrate from binding to the active site
d) i dont think adding a competitive inhibitor will increase the number of products bc competitive inhibitors decrease the reaction rate by blocking substrates from binding to the active site :/
e) false bc competitive inhibitors do not bind to the substrates; they bind to the active sites, thus blocking the substrate from entering the active site. u can see this in the blue-green square at the top figures
Answer: D. helps in digestion
Explanation: Gastric juice in the stomach contains HCL which creates an acidic condition(pH1.5-2.0) which is optimal for the action of enzymes in the stomach. HCL stops the activity of salivary amylase & helps to kill bacteria in food. It doesn’t help in digestion cuz it is not an enzyme.
Answer:
it stayed the same
Explanation:
Isotonic solution have an equal concentration of solute and solvent therefore there will be no net flow of water in either directions.
6CO2+12H2O+light->C6H12O6+6O2+6H2O
Answer:A. Protists B. Bacteria C. Animals D. Plants E. Fungi F. Archaea
Explanation:viruses are small non-living particles that contains hereditary materials.viruses attack cells of other organisms such as plants , bacteria ,archaea etc.
Viruses are acellular and contains either DNA or RNA.they cannot synthesis protein as they lack ribosomes ,so they use the ribosomes of the cell they have invaded to synthesize they proteins they need.
A virus usually has a central core surrounded by an outer protein coat called capsid.
Viruses can reproduce only within the living host cells and they are specific to the type of cells they attack.they attack plants through insect vectors or through openings on the plants.
Viruses can affect bacteria by injecting their nucleic acids through the cell wall and into the bacteria cell.such viruses are called bacteriophages.
