Explanation:
Parts of the microscope are:
1. Eyepiece or ocular. This what you look through at the top of the microscope.
2. Eyepiece tube. Holds the eyepiece in place
3. Objective lens. The primary optical lenses on a microscope ranging from 4x to 100x magnification power.
4. Nosepiece. Houses the objective.
5. Coarse and fine focus knobs. They are used to focus the microscope.
6. Stage. This is a ledge where the specimen to be observed is placed.
7. Stage clips. Clips on the stage that hold e.g. a glass slide on which the specimen has been mounted.
8.Aperture. The hole in the stage through which transmitted light from the base reaches a specimen placed on the stage for observation.
9. Illuminator. This is the light source for a microscope usually located in the base of the microscope.
10. Condensor. Is used to collect and focus the light from the illuminator on to the specimen. It is located immediately under the stage.
11. Iris diaphragm. This is a flexible structure that controls the amount of light reaching the specimen and is located above the condenser and below the stage.
12. Condensor focus knob. Moves the condenser up and down to control the light focus on the specimen.
13. Base. This is the foot of the microscope and supports the whole frame of the microscope.
Answer:
Option B, an allosteric inhibitor.
Explanation:
As the enzyme activity decreases, it is not possible for A to be a coenzyme (most likely would increase the enzyme activity), a substrate (increases activity of enzyme by Le Chatler's principle) or an intermediate (no effect). A is unlikely to be a competitive inhibitor as this would not decrease the activity of the enzyme, only reduce the rate of conversion of substrate to product. A is most likely an allosteric inhibitor which binds to another site on the enzyme (other than the active site), resulting in a change in conformation of the enzyme which reduces the enzymatic activity.
Answer: the answer is B
