Chapter 3: Carbon And The Molecular Diversity Of Life

Question 0

Macromolecules is?

Answer 0

On the Molecular scale, Members of three of these classes-Carbohydrates, Proteins, And nucleic acids are huge And therefore called Macromolecules.

Question 1

Organic compound

Answer 1

A compound containing carbon is said to be an organic compound. Furthermore almost all organic compounds associated with life contain hydrogen atoms in addition to Carbon Atoms.

Question 2

Carbon Adams form diverse molecules by bonding to four at times.

Answer 2

True

Question 3

The number of covalent bonds it can form Is:

Answer 3

Valence

Question 4

Hydrocarbons are:

Answer 4

Organic molecules consisting of only carbon and hydrogen.

Question 5

Functional group

Answer 5

The chemical groups affect molecular function by being directly involved in chemical reactions; these important Chemical groups are known as functional groups.

Question 6

Adenosine triphosphate is? (ATP)

Answer 6

A more complicated organic phosphate. It’s function in the cell is so important. ATP consists of an organic molecule called adenosine attached to a string of three phosphate groups

Question 7

Define Polymer.

Answer 7

A long molecule consisting of many similar or identical building blocks linked by covalent bonds, much as a train consists of a chain of cars.

Question 8

Define monomers:

Answer 8

The repeating units that serve as the building blocks of a polymer are small molecules.

Question 9

Enzymes are

Answer 9

Are specialized macromolecules (usually proteins) that speed up chemical reactions.

Question 10

Dehydration reaction

Answer 10

Monomers are connected by a reaction in which two molecules are covalently bonded to another, with loss of water molecule.

Question 11

Hydrolysis

Answer 11

The process that is essentially the reverse of dehydration reaction.
