1

The following is an example of which reaction class?

CH3CH2OH → CH3CHO + H2O

Elimination Reaction

2

The following is an example of which reaction class?

HOOCCH=CHCOOH + H2O → HOOCCH2CH(OH)COOH

Addition Reaction

3

The following is an example of which reaction class?

CH3Br + HSCH2CH(NH2)COOH → CH3SCH2CH(NH2)COOH + Br- + H+

Nucleophilic Substituition

4

The site of aerobic respiration is:

Mitochondria

5

The carbohydrate coat of a cell is called the:

Glycocalyx

6

Which of the following organelles is involved in aerobic metabolism?

Mitchondria

7

Prokaryotic cells lack:

nucleus

8

Nucleus

In eukaryotic cells. Contains the cell's genetic information and the machinery for converting that information into a code for protein synthesis.

9

Endoplasmic Reticulum

Constitutes more than half a cell's total membrane. It exists in two forms: rough and smooth. RER, externally studded with ribosomes, is primarily involved in protein synthesis. SER, lacks attached ribosomes, is involved in lipid synthesis, biotransformation, and Ca²⁺.

10

Isoelectric point (pI)

The pH at which an amino acid has no net charge. Calculated by (pK₁ + pK₂)/ 2.

11

Lysosomes

Vesicles that contain acid hydrolase enzymes, proteins that can degrade biopolymers (proteins, carbohydrates, and nucleic acids) and complex lipids.

12

What properties of water explains it's ability to dissolve acetic acid?

The ability to form hydrogen bonds with the carbonyl and the hydroxyl groups of acetic acid.

13

Two reasons the ability to form hydrogen bonds with other water molecules or with other polar compounds is important .

1) It gives water great cohesion and resistance to vaporization.
2) It allows for solvation of biomoecules which can also form hydrogen bonds.
