Q1. Where Does Glycolysis Occur In A Cell?

A. Cytoplasm
B. Mitochondria
C. Endoplasmic Reticulum
D. Plasma Membrane

ANSWER – A. Cytoplasm

• Explanation– Glycolysis Is A Metabolic Mechanism In Which Glucose Is Oxidized In The Presence Of Hydrogen Ions In The Cytoplasm. Glycolysis Produces Adenosine Triphosphate By Converting Glucose To Pyruvate. As Glucose Is Oxidized By Electron Transport In The Cytoplasm, The Process Of Glycolysis Takes Place In The Cytoplasm. It Is The Most Important Aspect Of Respiration. Glycolysis Occur In The Cytoplasm Of A Cell.

Q2. Which Of The Following Is Regenerated In The Urea Cycle?

A. Oxaloacetate
B. Ornithine
C. Fumarate
D. Argino-Succinate

ANSWER – B. Ornithine

• Explanation – The Urea Cycle (Also Known As The Ornithine Cycle) Is A Series Of Biological Events That Convert Ammonia Into Urea (NH2)2CO (NH3). This Cycle Occurs In Ureotelic Organisms. The Urea Cycle Transforms Highly Toxic Ammonia Into Urea, Which Is Then Excreted. Ornithine Is A Non-Essential Amino Acid That Is Created As A Byproduct Of The Urea Cycle.

Q3. Which Of The Following Is Not An Enzyme Of Protein Digestion?

A. Trypsin
B. Pepsin
C. Ptyalin
D. Chymotrypsin

ANSWER: C. Ptyalin

• Explanation: The Enzyme Amylase, Also Known As Ptyalin, Is Found In Saliva And Is Capable Of Breaking Down Starch Into Simpler Sugars Like Maltose And Dextrin, Which Can Then Be Broken Down Further In The Small Intestine. It Has A Role In Carbohydrate Digestion And Is Not Involved In Protein Digestion.

Q4. Beta-Oxidation Of Palmitic Acid Results In ________ Acetyl CoA.

A. 5
B. 6
C. 7
D. 8

ANSWER – D. 8

• Explanation – Oxidation Of Palmitic Acid Yields 7 NADH + 7 FADH2 + 8 Acetyl-CoA In 7 Cycles Of Mitochondrial Beta-Oxidation. Therefore, The Number Of Acetyl CoA Is 8. Acetyl-CoA Generated By The Beta-Oxidation Pathway Enters The Mitochondrial TCA Cycle, Where Is Further Oxidized To Generate NADH And FADH₂.

Q5. NADPH Is Generated In The ________ Pathway.

A. Glycogenesis
B. Gluconeogenesis
C. HMP Shunt
D. Glycolysis

ANSWER: C. HMP Shunt

• Explanation: The HMP Shunt Also Known As Pentose Phosphate Pathway Generates NADPH And Synthesizes Five-Carbon Sugars. All Organisms Require A Source Of NADPH For Reductive Biosynthesis, And The Pentose Phosphate Route Provides That.
