Frage 1
Frage
Which statement about the smooth endoplasmic reticulum is INCORRECT?
Antworten
-
The sER metabolises carbohydrates.
-
The sER synthesizes lipids.
-
The sER detoxifies drugs and poisons (non-nutritional chemicals).
-
The sER stores calcium.
-
The sER synthesizes proteins.
Frage 2
Frage
The amount of sER can increase or decrease according to a cell's demands.
Frage 3
Frage
The rough endoplasmic reticulum contains [blank_start]ribosomes[blank_end], and is the site of most [blank_start]protein[blank_end] synthesis. It also stores protein in the lumen, its [blank_start]interior[blank_end].
Antworten
-
ribosomes
-
nucleic acid
-
protein
-
lipid
-
interior
-
exterior
Frage 4
Frage
Synthesis of cytoplasmic proteins occurs in the rER.
Frage 5
Frage
Which statement about the Golgi is NOT correct?
Antworten
-
The Golgi has polarity, and is responsible for processing proteins from the rER.
-
The Golgi glycosolates proteins (adds sugars) and modifies simple carbohydrates to make complex carbohydrates.
-
Vesicles tagged for the plasma membrane exit the trans side of the Golgi.
-
Proteins destined to return to the rER to maintain its structure leave the Golgi in vesicles via the cis face.
Frage 6
Frage
The Golgi tags proteins so they are directed to the proper vesicle, and then tags those vesicles to direct them to the correct target compartment.
Frage 7
Frage
There are two pathways from the Golgi out of the cell. These [blank_start]exocytosis[blank_end] pathways can be continuous and unregulated, or "[blank_start]Constitutive[blank_end]" pathways (e.g. proteins transported to the ECM) or they can be "[blank_start]Regulated[blank_end]" pathways, for example the release of [blank_start]hormones[blank_end].
Antworten
-
exocytosis
-
Constitutive
-
Regulated
-
hormones
Frage 8
Frage
[blank_start]Phagocytosi[blank_end]s is a type of endocytosis which is selective, and uptakes "food" to "eat". [blank_start]Pinocytosis[blank_end] however is the non-selective uptake of solutes. Endocytosis can also uptake [blank_start]very specific[blank_end] molecules via [blank_start]receptor mediated[blank_end] endocytosis.
All of these pathways join their vesicles with [blank_start]lysosomes[blank_end] for digestion.
Antworten
-
Phagocytosis
-
Pinocytosis
-
very specific
-
receptor mediated
-
lysosomes
