MULTIPLE CHOICE
1) The Water Content In The Human Body Is Approximately :
A) 90%.
B) 80%.
C) 70%.
D) 60%.
E) 50%.
ANS. C
Objective: 1.2 Global LO: G7
Water Is The Most Abundant Component Of The Human Body And Serves As The
Medium For Nearly All Biochemical Reactions. On Average, About 70% Of Body Mass
Is Water, Although This Percentage Can Vary Slightly With Age, Sex, And Body
Composition. Water’s Polarity And Hydrogen-Bonding Ability Make It Essential For
Dissolving Ions, Transporting Nutrients, And Regulating Temperature.
2) The Four Most Abundant Chemical Elements In Living Systems Are :
A) Hydrogen, Oxygen, Sulfur And Phosphorus.
B) Hydrogen, Carbon, Nitrogen And Oxygen.
C) Sodium, Potassium, Carbon And Oxygen.
D) Sodium, Potassium, Nitrogen And Sulfur.
E) Carbon, Nitrogen, Oxygen And Potassium.
ANS. B
, Objective: 1.2 Global LO: G7
Living Organisms Are Primarily Composed Of Carbon, Hydrogen, Nitrogen, And
Oxygen (CHNO). Carbon Forms The Backbone Of Organic Molecules, Hydrogen And
Oxygen Are Major Components Of Water And Organic Compounds, And Nitrogen Is
Essential For Amino Acids And Nucleotides. Together, These Four Elements Account
For The Vast Majority Of Cellular Mass.
3) Nearly All Proteins Contain :
A) Cobalt.
B) Phosphorus.
C) Selenium.
D) Sulfur.
E) None Of The Above.
ANS. D
Objective: 1.2 Global LO: G7
Most Proteins Contain Sulfur Because The Amino Acids Cysteine And Methionine
Include Sulfur Atoms. Cysteine Is Especially Important For Forming Disulfide Bonds,
Which Stabilize Protein Structure. While Not Every Protein Contains Sulfur, It Is Present
In Nearly All Proteins.
4) Which Of The Following Statements Is FALSE?
A) Proteins Can Be Structural Components Of Cells.
B) Proteins Can Transmit Signals Between Cells.
C) Proteins Can Transport Molecules Within Cells And Between Cells.
D) Proteins Can Be Both Hormones And Hormone Receptors.
E) Proteins Are The Only Biological Polymer That Can Catalyze Biochemical Reactions.
ANS. E
