Biological Molecules

Question 1

what are all living things made of and what are organic molecules?

Answer 1

made of organic molecules (is a carbon containing molecule, where carbon acts as a backbone structure)

Question 2

what are the main four types of biological molecules?

Answer 2

nucleic acid, carbohydrates, lipid, protein (are all polymers)

Question 3

what do all biological molecules contain?

Answer 3

carbon, hydrogen, oxygen

Question 4

what does protein and nucleic acid contain?

Answer 4

protein ( contains nitrogen & sulfur), Nucleic acid (nitrogen & phosophate)

Question 5

How are large molecules made from smaller moleclules?

Answer 5

made by a condensation reaction (a bond forms between them and a water molecule is produced)

Question 6

How are large molecules broken down?

Answer 6

By a hydrolsis reaction (water molecule is used to break downa bond)

Question 7

How are properties of a biological molecule altered?

Answer 7

By the absence or presence of functional groups

Question 8

whatare the functional groups?

Answer 8

Hydroxl (OH), carboxyl (C,O,OH), phosphate, Amino (NH2)

Question 9

What happens to the functional groups when we add a group or take away a group?

Answer 9

Adding a group we add “ation” to the end (example= hydroxlation), Taking away a group we add “de” (example= dehydroxlation)
