Question

An organelle found in plant sells that controls rigidity is called Central vacuole Rough Endoplasmic Reticulum Chloroplasts Lysosomes Mitochondria Why is cellulose so difficult for most animals to digest? they don't have the proper enzyme to break the bonds between subunits cellulose is made up of chitin, which is indigestible the bonds holding cellulose subunits together are extremely strong, stronger than in any other macromolecule there are many hydrogen bonds holding the subunits together Glycosidic bonds are associated with: Carbohydrates Proteins Nucleic Acids Lipids All of the above Which of the following is not part of the structure of DNA? A nitrogenous base Glycerol A Sugar Phosphate groups All the above are part of the structure Immediate energy in the cell is in the form of: Triglycerides Phospholipids Glucose ATP Glycogen Which of the following is NOT found in phospholipids? A Carbohydrate Fatty acids Phosphates Glycerol All the above are found in phospholipids Water is said to have a dipole. Which of the following most accurately describes this property: Water has adhesive properties Water is thus partly negative and partly positive Water contains hydrogen bonds Frozen water is less dense than liquid water All are true Ribose is a carbohydrate composed of 5 carbons. It is therefore termed a: Pentose Hexose Triose Disaccharide Polysaccharide

Explanation / Answer

Ans-23- option a is correct I.e. central vacuole.

Ans-24- option a is correct I.e. they don't have proper enzyme to break cellulose.

Ans-25- option a is correct i.e.they are associated with carbohydrate.

One group will be carbohydrate, other group may be carbohydrate or something else.

Ans-26 option c is correct I.e. glycerol.

Ans-27- option d is correct I.e. ATP.

Ans-28-option a is correct I.e. carbohydrate.

Ans-29- option b is correct I.e water has partly positive charge and partly negative charge.

Ans-30- option a is correct I.e. pantose.
