Upon cellular injury, which metabolic process is involved during the growth and repair phases of the cell?
- Ans:✔✔-The anabolic process would be active as it is involved in the building up of small complexes
into larger ones
What is one of the main functions of light reactions? - Ans:✔✔-Similar to the electron transport chain,
one of its main functions is to generate a proton concentration gradient to generate ATP.
True of false: Dark reactions can occur in the presence or absence of light - Ans:✔✔-true
assuming a constant (non-adjustable) light source power, identify the part of the microscope you would
adjust to limit the amount of light entering the microscope? - Ans:✔✔-iris diaphragm
What is the total magnification (relative to the eye) of a sample imaged with a 60x objective and a 10x
eyepiece? show your math - Ans:✔✔-60 x 10 = 600x magnification
Identify what type of electron microscope was used to capture the following image and explain your
choice. - Ans:✔✔-The image was captur4ed using a scanning electron microscope (SEM). The above
image shows the trademark shell image (no subcellular organelles are visible) reminiscent of SEM. Only
TEM is capable of visualizing subcellular structures.
True or false: LB agar is classified as a selective, non-differential media - Ans:✔✔-false
What is agar used for in microbiology? - Ans:✔✔-Agar is used to create a solid, smooth surface on which
