Question 9

Match the vitamins on the left with the appropriate descriptions on the right.
-Niacin
A) Deficiency causes scurvy
B) Important in NAD
C) Absorption requires intrinsic factor
D) Helps to regulate calcium levels

Accepted Answer

Niacin is a key component of NAD (nicotinamide adenine dinucleotide), which is essential for energy production and metabolism in the body.

Question 10

Match the vitamins on the left with the appropriate descriptions on the right.
-D
A) Deficiency causes scurvy
B) Important in NAD
C) Absorption requires intrinsic factor
D) Helps to regulate calcium levels

Accepted Answer

Helps to regulate calcium levels

Question 11

Match the vitamins on the left with the appropriate descriptions on the right.
-C
A) Deficiency causes scurvy
B) Important in NAD
C) Absorption requires intrinsic factor
D) Helps to regulate calcium levels

Accepted Answer

Vitamin C deficiency causes scurvy, characterized by symptoms such as bleeding gums and joint pain.

Question 12

Match the vitamins on the left with the appropriate descriptions on the right.
-B12
A) Deficiency causes scurvy
B) Important in NAD
C) Absorption requires intrinsic factor
D) Helps to regulate calcium levels

Accepted Answer

Vitamin B12 absorption in the gut requires the presence of intrinsic factor, a protein produced by cells in the stomach lining. Without intrinsic factor, vitamin B12 cannot be efficiently absorbed, leading to potential deficiencies.

Question 13

Match the enzymes on the left with the appropriate descriptions on the right.
-Amylase
A)Begins protein digestion
B)Acts on trypsinogen
C)Responsible for fat digestion
D)Present in saliva

Accepted Answer

Amylase is an enzyme present in saliva that begins the process of starch digestion in the mouth.

Question 14

Match the enzymes on the left with the appropriate descriptions on the right.
-Pepsin
A)Begins protein digestion
B)Acts on trypsinogen
C)Responsible for fat digestion
D)Present in saliva

Accepted Answer

Pepsin is an enzyme in the stomach that starts the digestion of proteins by breaking them down into smaller peptides.

Question 15

Match the enzymes on the left with the appropriate descriptions on the right.
-Lipase
A)Begins protein digestion
B)Acts on trypsinogen
C)Responsible for fat digestion
D)Present in saliva

Accepted Answer

Lipase is responsible for breaking down fats into fatty acids and glycerol, making it crucial for fat digestion.

Question 16

Match the enzymes on the left with the appropriate descriptions on the right.
-Enterokinase
A)Begins protein digestion
B)Acts on trypsinogen
C)Responsible for fat digestion
D)Present in saliva

Accepted Answer

Enterokinase acts on trypsinogen to activate it into trypsin, which then participates in protein digestion. It does not directly digest proteins, fats, or is present in saliva.

Question 17

Match the enzymes on the left with the appropriate descriptions on the right.
-Pepsinogen
A) Activated by HCl(aq)
B) Pancreatic starch digesting enzyme
C) Acts on a dissacharide
