Hypotonic =

Hypertonic =

Answer 8

Isotonic = 0.95% NaCl & 5.5% Glucose

Hypotonic = less than 0.95% NaCl & 5.5% Glucose

Hypertonic = more than 0.95% NaCl & 5.5% Glucose

Question 9

Inversely related

Question 13

Daltons Law of PP

Answer 13

Total Pressure of Gase = Sum of partial pressures

Question 14

What is the solubility of a Gas:

Answer 14

For all gaseous solutes, an increase in temp leads to a decrease in solubility.

Question 15

Define: Electrolytes

Answer 15

Compounds that dissolve in water to form ions

Question 16

Bronsted-Lowry Acids & Bases:

Acids _______ H⁺

Bases _______ H⁺

Acids are proton _______.

Bases are proton _______.

Answer 16

Acids release H⁺

Bases accept H⁺

Acids are proton donors.

Bases are proton acceptors.

Question 17

Bronsted-Lowry Acids & Bases:

Define: Amphoteric

Answer 17

Amphoteric: Compounds that can act as acids or bases.

i.e: H₂O

Question 18

Ka values for selected acids:

Which of the following is stronger?

K_a = 2.5 x 10¹⁰

OR

K_a = 6.6 x 10^-4

(K_a refers to acids, different than K_eq)

Answer 18

K_a = 2.5 x 10¹⁰ is the stronger acid.

fyi: (larger values are stronger acids)

Question 19

1. Monosaccharides:
2. Oligosaccharides:
3. Polysaccharides:

Answer 19

1. Monosaccharides: Glucose/polyhydroxy aldehydes or ketones.
2. Oligosaccharides: Lactose/contains 2-10 monosaccharide residues.
3. Polysaccharides: Starch/contain more than 10 monosaccharide residues.

Question 20

Net Harvest from one go around of CA cycle is what?

Answer 20

3 NADH

1 FADH₂

1 ATP

Question 21

(fatty acid catabolism)

NADH to ATP conversion

FADH₂ to ATP conversion

Answer 21

NADH X 2.5

FADH₂ X 1.5

Question 22

ATP’s produced from total oxidation (fatty acid catabolism)

NADH =

FADH_{2 =}

acetyl-CoA =

ATP =

Answer 22

NADH = Number of breaks _{(lines @ 2 cabons)}

FADH_{2 =} NADH
