2. glucose monomers forming unbranched chains with only beta 1, 4 linkages

3. glucose monomers forming unbranched chains with only alpha 1, 4 linkages

1. forms peptide bonds
2. component of ribosome
3. all of these
4. Is a 23s rRNA

Q. Cellulose is a ________.

1. Hexosan polysaccharide

Q.

Which of the following occurs during the light-dependent reactions of plants?

1. splitting of water

2. electron transport

3. chemiosmosis

4. all of the above

Q.

What is the formula of starch?

Q.

What is Chlorophyll? Where is it found in plants?

Q.

What is the advantage of storing glucose as glycogen in animals instead of as monomeric glucose?

1. Energy obtained from glycogen is more than that from the corresponding glucose monomers.

2. Glucose present as monomers within the cell exerts more osmotic pressure than a single glycogen molecule, resulting in loss of water from the cells.

3. Glucose present as monomers within the cell exerts more osmotic pressure than a single glycogen molecule, resulting in excess water within the cells.

4. Glycogen gives more rigidity to the cells.

Q.

What organ controls the level of glucose in blood?

Q.

Q. Cell walls of fungi are composed primarily of

1. lignin
2. cellulose
3. chitin
4. pectin

Q. Lactose is composed of

1. Glucose + fructose
2. Glucose + glucose
3. Glucose + galactose
4. Fructose + galadose

Q.

The chemical nature of chitin is ___?

Q.

What are carbohydrates

Q.

Name the part of the chloroplast where the light reaction takes place.

Q. Which one of the following is a non-reducing sugar?

1. Cellulose
2. Lipids
3. Protein
4. Steriods

Q. Mention a single membrane bound organelle which is rich in hydrolytic enzymes.

Q. Humans cannot digest cellulose whereas cows can do so because

1. Their gut contains certain bacteria capable of digesting cellulose.
2. They have a many-chambered stomach.
3. They have efficient grinding molars.

1. Lipase
2. Trypsin
3. Rennin
4. Pepsin
