Biochemistry

Question 1

The relationship between pH and hydrogen ion concentration

Answer 1

As the pH value goes down, a substance becomes more acidic because there are more free hydrogen ions in solution

Question 2

As the pH value goes up, a substance becomes more basic because there are fewer free hydrogen ions in solution

Answer 2

True

Question 3

Buffers in cells

Answer 3

They help regulate pH levels so things don’t become too EXTREME

Question 4

Cohesion/Adhesion

Answer 4

Hydrogen bonds that hold water molecules together, allowing them to adhere to each other and other hydrophilic surfaces

Question 5

Cohesion/Adhesion

Answer 5

Allows water to act as a transport

Question 6

High Specific Heat

Answer 6

Needs more energy to break the Hydrogen bonds

Question 7

High Specific Heat

Answer 7

Helps regulate temperature changes in the wild

Question 8

Ice Floats

Answer 8

When water molecules freeze, the hydrogen bonds hold them father apart than when water is liquid

Question 9

Ice Floats

Answer 9

Can act as an insulator, protects organisms from freezing

Question 10

Water is universal solvent

Answer 10

Polar so it can dissolve a wide array of things that are also polar

Question 11

Water is universal solvent

Answer 11

Most chemical reactions use water to dissolve things
