Question 1

Which molecule is chiral?

Accepted Answer

The answer of Which molecule is chiral? 
...

Question 2

Which disaccharide has glycosidic bonds to the anomeric carbons of both monosaccharides?

Accepted Answer

Sucrose is unique among the common disaccharides in having a glycosidic bond that links the anomeric carbon of glucose to the anomeric carbon of fructose, making it a non-reducing sugar.

Question 3

...

Question 4

Which carbon(s)in the Fischer projection below is/are a chirality center?

Accepted Answer

The answer of Which carbon(s)in the Fischer projection below is/are...

Question 5

Which statement BEST explains how mutarotation occurs in solution?

Accepted Answer

Mutarotation occurs when the bond between the ring oxygen and the anomeric carbon breaks, allowing the ring to open. The open-chain form can then rotate freely, and when the ring closes again, the hydroxyl group on the anomeric carbon can attach in a different orientation, resulting in a change between the α and β forms of the sugar.

Question 6

Which carbon(s)in the Fischer projection below is/are a chirality center?

Accepted Answer

The answer of Which carbon(s)in the Fischer projection below is/are...

Question 7

Most animals cannot digest cellulose.However, those with a second stomach, containing specific bacteria that produce β-glycosidases, can digest cellulose.What is the role of the β-glycosidase in digesting cellulose?

Accepted Answer

β-glycosidase catalyzes the hydrolysis of cellulose, breaking down the β-glycosidic bonds between the glucose units in cellulose, making it digestible for the animals.

Question 8

Which disaccharide is composed of two glucose molecules?

Accepted Answer

Cellobiose and maltose are both disaccharides composed of two glucose molecules. Cellobiose is a structural component of cellulose in plants, and maltose is formed from the enzymatic breakdown of starch.

Question 9

The Fischer projection for fructose is shown below.Fructose is a(n)_______.

Accepted Answer

The answer of The Fischer projection for fructose is shown...

Question 10

Insulin acts to __________, whereas glucagon __________.

Accepted Answer

Insulin decreases blood sugar levels by facilitating the uptake of glucose into cells, while glucagon increases blood sugar levels by stimulating the conversion of stored glycogen into glucose in the liver.

Question 11

A large molecule composed of many repeating units of smaller molecules is called a

Accepted Answer

Polymers are large molecules made up of many repeating units known as monomers. These can be naturally occurring, like proteins and DNA, or synthetic, like plastics.

Question 12

Which disaccharide is the common type of sugar that comes from sugar cane or beets?

Accepted Answer

Sucrose is the common type of sugar derived from sugar cane or beets, widely used in food.

Question 13

The result of a patient's fasting plasma glucose test is 60 mg glucose per deciliter.This patient is

Accepted Answer

A fasting plasma glucose level of 60 mg/dL is considered low, indicating hypoglycemia. Normal fasting glucose levels typically range from 70 to 99 mg/dL.

Question 14

The ring structure shown below left is called a ________, and the ring structure to the below right is called a _________.

Accepted Answer

The answer of The ring structure shown below left is...

Question 15

Which is the BEST definition for diabetes?

Accepted Answer

Diabetes is characterized by hyperglycemia (high blood sugar levels) resulting from the body's inability to use blood glucose for energy. This can be due to insulin resistance, where the body's cells do not respond properly to insulin, or insufficient insulin production by the pancreas.

Question 16

Which statement BEST describes at the molecular level why AB is the universal recipient?

Accepted Answer

Blood type AB is considered the universal recipient because its red blood cells have both A and B antigens on their surface. This means individuals with AB blood can receive red blood cells from any other blood type without their immune system attacking the donated cells, as their immune system recognizes both A and B antigens as self.

Question 17

Which structure is a monosaccharide?
