Q

What determines the amount of movement on tlc chromatography?

A

The plate is usually polar so more polar objects will also bind to the plate. Nonpolar molecules will travel faster during the mobile phase.

Q

Contrast the terms stereoselective and Stereospecific:

A

Selective” implies that there are factors which favor one product over the other, while “specific” is usually a sign that there’s something inherent to the mechanism that leads to only one product.

Q

What does a gas-liquid chromtography measure?

A

It separates molecules based on their molecular weight and intermolecular forces.

Molecules with lower bp, low weight will travel faster than molecules with high bp, high weight.

Restore balance towards the resting potential by removing 3 Na out and moving 2 K in.

24
Q

Do RBC have DNA?

A

No.

25
Q

What are behavioralist in psychology?

A

Behavioralism is a systematic approach to the understanding of human and animal behavior. It assumes that the behavior of a human or an animal is a consequence of that individual’s history, including especially reinforcement and punishment, together with the individual’s current motivational state and controlling stimuli.

26
Q

What is the optimal arousal theory?

A

optimal performance requires optimal arousal; it won’t work if it’s too high or too low.

27
Q

What is Seyle’s adaptation theory?

A

people’s responses to stressors are generally similar

28
Q

A
  1. psychological conflict that results when a choice must be made between two undesirable alternatives
  2. psychological conflict that results when a choice must be made between two desirable alternatives
  3. psychological conflict that results when a goal is both desirable and undesirable
29
Q

What is linguistic relativity?

A

The worphian hypothesis. Language determines though.

30
Q

Contrast role strain vs role conflict

A

Role strain is with one role

Role conflict is maintaining two different roles.

31
Q

What is a mixed methods study?

A

Both qualitatively and quantitatively

32
Q

Describe cDNA lib formation:

A
  1. Allow transcription to occur and the process of splicing.
  2. Take the mRNA after splicing and use reverse trascriptase to form complementary DNA without introns.
  3. Amplify with dna replication.
33
Q

What is glycogenolysis

A

breaking down of glycogen storages in the hepatocytes.

34
Q

Which molecules can be used to stimulate gluconeogenesis?

A

lactate, oaa, alpha ketogluterate, Amino Acids, Glycerol, and Propionate

35
Q

Describe g linked receptors.

A
  1. ligand binds to receptor.
  2. gdp to gtp and moving alpha to adenylate cylase
  3. conversion of atp to camp, activate protein kinase a.
  4. activation of cascade.
36
Q

What is parallel progressing?

A

the ability to quickly gain information, through the eyes, about color, form, and motion.
spatial– not moving
temporal– moving.

37
Q

Relate homeostasis with drug addictions:

A

your body becomes habituated to drugs and will attempt to help you prior to injections. you will never feel the same effect as your first time because of homeostatic regulations. this can include time and place.

38
Q

Describe contralateral brain function

A

left brain controls right side of the body
right brain controls the left side of the body.

left brain: verbal, language, and analytics
right brain: creativity, emotion, conceptual.

39
Q

What is the eventual result of cognitive dissonance?

A

People are doing behaviors they know are typically harmful to them. Over time, the end results is that people will change their thinking so that the behavior, in their mind, will not be as bad.

40
Q

Where is the highest blood pressure in the body?

A

Aorta.

41
Q

What is the average weight of an amino acid?

A

110 Daltons

42
Q

Describe Hills Coefficient

A

> 1 : Positive Cooperative Binding

=1: No cooperative binding

43
Q

Compare native vs reducing SDS

A

Reducing separates disulfide bonds while native doesn’t.

44
Q

How does an uncompetitive inhibitor work?

A

Substrate binds to active site first THEN the inhibitor binds causing inhibition. Decreases both vMax and Km proportionally.

45
Q

Gluconeogenesis precursors

A

lactate, oxaloacetate, and glycerol.

46
Q

How can you easily identify kerb cycle enzymes?

A

the name of the enzyme is the name of the substrate before it.

47
Q

list stomach cells

A

Chief Cells: pepsinogen

Parietal Cells: HCL

48
Q

intestinal enzymes:

A

enterokinase: converts trypsinogen to trypsin.
secretin: stimulates pancreas
