Intro to Bio Macromolecules

Question 1

Polarity

Answer 1

the property of a neutral, uncharged molecule having an asymmetric internal distribution of positive charge

Question 2

Covalent single bond

Answer 2

Sharing 1 pair of electrons

Question 3

Ionic bond

Answer 3

Transfer of electrons, forms salts

Question 4

Metallic bonds

Answer 4

attraction between metal ions and sea of delocalized electrons

Question 5

Polymers are bonded by

Answer 5

Covalent bonds

Question 6

Intramolecular bonds

Answer 6

within particles

Question 7

Intermolecular bonds

Answer 7

between molecules

Question 8

Dehydration synthesis

Answer 8

condensation reaction, requires energy (endergonic reaction) and enzymes, anabolic (builds complexity)

Question 9

Hydrolysis

Answer 9

Releases energy (exergonic) and enzymes, catabolic (reduces complexity)

Question 10

Plants get carbon from

Answer 10

the CO2 in the air

Question 11

Animals get carbon from

Answer 11

consuming plants and other animals

Question 12

Plants convert the CO2 in the air into

Answer 12

carbohydrates, which then can be used to produce lipids and proteins

Question 13

Animals release carbon by

Answer 13

exhaling CO2
