Flashcards in Review 4 Deck (35):
1

Is HF a strong or weak acid?

Weak acid

- Small => not much room to distribute negative charge => doesn't want to lose H

2

Galvanic cell's Ecell

Positive b/c spontaneous

- Releases energy

3

Formula relating capacitance and voltage

C = q/V

4

Difference b/w -ous and -ic acids

-ous acids have 1 fewer O than -ic acids

- Ex. Phosphorous acid = H3PO3
- Phosphoric acid = H3PO4

5

Electrons are passed from carriers with _____ reduction potential to _____ reduction potential

Lower to higher

- Higher reduction potential = greater potential to be reduced (gain e-)

6

What does glucagon do?

Stimulates liver to carry out glycogenolysis (break down its stored glycogen into glucose)

7

What is Go phase?

Phase that cell enters if it does not need to divide

8

What kind of solvents is Sn2 favored by?

Polar, aprotic solvents

- Ex. DMSO, acetone

9

Passive immunity

Transfer of active humoral immunity (ready-made Ab) from one indiv to another

10

What is responsible for cell differentiation?

Gene expression

11

Ecological validity

How experiment applies to environment

12

Free choice paradigm

Reduction of conflict when person has binary choice that conflicts with values => change attitudes to be congruent w/ decision

13

Post-decisional conflict

Dissonance from behaving in counter-attitudinal way

14

Informational influence

Accept info of others

15

Internal consistency

How well items of study assess construct of interest

16

Explicit attitudes

Conscious attitudes (that you are aware of)

17

Mechanical energy

Made of potential and kinetic energy

- Depends on motion and position of object

18

Efficiency formula

Work output/work input

19

Is perchloric acid strong or weak?

Strong

20

Rules for aromaticity

Sp2 (fully planar)
4n+2 pi electrons (Huckel's rule)
Fully conjugated

21

Antiaromatic

4n pi electrons
Planar and conjugated

22

Nonaromatic

Not conjugated or not sp2 (not planar)

23

Calcitonin

Decreases plasma Ca2+ by increases osteoblasts

24

Kinematics formulas

v = vo + at
v2 = vo2 + 2a∆x
∆x = vot + 1/2at^2
∆x = t*(v+vo)/2

25

Thin lens equation

1/ƒ=1/do+1/di

- di = image distance
- do = object distance
- f = focal length

26

Power of lens

1/focal length

27

Converging lens (real/virtual, etc.)

Real, inverted when outside focal length
Virtual, upright when inside focal length

28

Concave lens

Vitual, upright, reduced

- VUR

29

What are microfilaments composed of?

Actin

30

Hill coefficient > 1

Cooperativity

31

How do noncompetitive inhibitors bind E and/or ES complex?

Both with same affinity

32

Weight of an amino acid?

110 Da

33

Relate ∆G and Keq

∆G = -RTln(Keq)

34

What kind of peptides bind to anion-exchange column?

Anions (net negative charge)

35

Relation b/w G and E

∆G = -nFE
