Human Physiology Unit 02 Exam Review A- Cell Signaling/ Endocrine
Test Description: Review part 1
Instructions: Answer all questions to get your test result.
1) An endocrine gland is distinct from an exocrine gland in that it
A
is considered an 'effector'
B
delivers its secretions with the help of carrier proteins
C
delivers its secretions to the bloodstream via a duct or tube
D
delivers its secretions to the bloodstream directly
2) paracrine regulation involves __________; while autocrine involves________
A
hormones that inhibit the production of others ; hormones that inhibit their own production
B
different cell types in the same tissue/ organ ; same cell type
C
activation/ inhibition of an adjacent gland ; self regulation by a gland via negative feedback
D
hormones that are delivered to multiple tissue types; delivery to only one tissue
3) Steroids, Melatonin, and Thyroid Hormones
A
bind to surface receptors that are dimers
B
all use cAMP as a second messenger
C
are all made from metalloproteins
D
are all lipophyllic
4) _________ hormones bind to surface receptors, while ________ bind to receptors inside the cell as they can permeate the cell membrane
A
Polar, Lipophyllic
B
First Messenger, Second Messenger
C
Receptor Mediated, CREB
D
Nuclear, Ligand
5) a prohormone like pro-opiomelanocortin can be cleaved to form
A
more than one functional hormone
B
two dimers, which allow it to bind to nuclear receptors
C
a post hormone, like Estrogen
D
a prehormone, that then becomes a functional hormone through iodination
6) Steroid hormones, which are all derived from _________, can be _____________, from the adrenal cortex, or sex hormones, which are made in the_____
A
Short polypeptides, Corticosteroids, Testis, Ovaries, etc.
B
Membrane Phospholipids, Adrenosteroids, Gonads
C
Cholesterol, Prostaglandins, Pituitary Gland
D
Cholesterol, Corticosteroids, Gonads
7) some hormones are also function as _________ in the nervous system
A
selective reuptake inhibitors
B
neurotransmitters
C
nutrients
D
glial regulators
8) the effect of all hormones is dependent on their ____________ in the ________ ____________
A
concentration, blood plasma
B
persistence, synaptic cleft
C
affinity, binding site
D
modification, target cell
9) ______ is the time required for the concentration to drop by 50%
A
half- life
B
dwell time
C
persistence
D
clearance
10) Synergistic hormones can be _______, where the effects 'stack'; or _________ where....
A
associative, complimentary.... multiple hormones are needed to achieve the target effect
B
additive; permissive... one hormone enhances the responsiveness of the cell to the other
C
homeodimers, heterodimers; ... different types of hormones come together to trigger the effect
D
summative; facultative... one hormone increases the concentration of the other
11) Although they are ___________, insulin and glucagon do not inhibit the actions of each other
A
reciprocal
B
synergistic
C
conflated
D
antagonistic
12) Some hormones bind to nuclear receptor proteins, forming functional ________ that activate or inhibit specific ________ ______
A
Catalyases; second messenger cascades
B
Transcription Factors, Gene Expression
C
G- protein complexes, Adenylate Cyclase
D
post hormones, cellular processes
13) while the cAMP pathway generally activates protein kinases, the phospholipase C pathway
A
triggers the release of calcium ions
B
leads to fusion of vesicles bearing specific carrier proteins to the cell membrane
C
leads to the opening of ion channels in the cell membrane
D
phosphorylates glycoproteins
14) In the Tyrosine Kinase pathway, used by _________, the receptors are unique in that they are ______
A
glucagon, G-protein mediated
B
Insulin, dimers
C
apoptosis hormones, polyphylic
D
Thyroxine, Iondinated
15) The anterior pituitary gland releases its hormones, which primarily__________, in response to
A
suppress anabolic reactions, decrease in ATP availability
B
regulate circadian rhythms, hormones from the pineal gland
C
regulate fluid homeostasis, innervation from the cerebellum
D
activate other glands, hormones from the hypothalamus
