   2. All cells possess a nucleus                        d. All cells come from meiosis

3. What is the most important cellular organelle for cellular respiration and specifically the cellular metabolic synthesis of adenosine tri-phosphate (ATP)?

4. Which of the following biochemical molecules can the human body extract chemical energy from to conduct mechanical work or anabolic synthesis?
   1. Glucose, Fructose, Sucrose                      d. Glycogen stored in liver & muscle
   2. Essential amino acids                               e. Fatty acid chains
   3. All of the above (A, B, D, E)                      f. None of the above (A, B, D, E)

Answer 1

1)What of the following is NOT included as one of the major components of the plasma membrane as described via the “Fluid Mosaic Model”

1. Lipids/fatty acids                                      c. Peripheral proteins
2. Nucleic acids                                             d. Integral proteins

The correct answer is Nucleic acids. The Fluid Mosaic Model establish a model for the components of the cell membrane including the lipid bilayer (Lipids/fatty acids), peripheral proteins and integral proteins which several functions such as" transport of nutrients and cell signaling.

2)Which of the following statement is true regarding biological life & cell theory?

1. All organisms are made of cells                c. All cells come from mitosis
2. All cells possess a nucleus                        d. All cells come from meiosis

The correct answer is All organisms are made of cells. This theory establish that all living organisms are made of cells as the smallest functional unit. The basic hierarchy is: Cells, Tissue, Organ, System and living being.
