The image below is an organelle that performs photosynthesis. Which of the following molecules is a reactant in the light dependent reactions? (Hint: it comes into the thylakoids and is split to begin the light dependent reactions. This is Molecule 1 in Figure 1).

Figure 5 below depicts a cross section of an organelle responsible for photosynthesis. What is Structure 2 in Figure 5?

Anaerobic cellular respiration means respiration that does NOT require oxygen.

Oxidation and reduction are important processes involved in cellular respiration and photosynthesis. Imagine there is a molecule of NAD+ that enters cellular respiration; it comes into glycolysis and becomes NADH when it exits the process. NAD+ absorbed two electrons, was it oxidized or reduced? (Hint: remember OIL RIG).

All cells have mitochondria.

Figure 9 below depicts a part of mitosis. What is structure 4 in the image?

46.  Which of the following is a common clinical presentation of a fracture?  

47.  A 50-year-old male presents with dyspnea, chest tightness, and a history of exposure to occupational dust. Which condition should be considered in the differential diagnosis?

Our day at the spa included getting manicures, we had facials, and we enjoyed a massage.
