organelles

Question 1

what is the function of mitochondria?

Answer 1

• energy production
• synthesis of proteins using own DNA

Question 2

whats the function of endoplasmic reticulum?

Answer 2

• calcium storage
• lipid production
• synthesis of proteins targeted to the plasma membrane

Question 3

whats the function of golgi apparatus?

Answer 3

• modification of proteins and lipids from the er
• transfer of proteins to other organelles

Question 4

whats the function of lysosomes?

Answer 4

digestion of unwanted organelles

Question 5

function of peroxisomes?

Answer 5

oxidative reactions

Question 6

which complexes are help proteins get from the cytosol to the interior of the mitochondria?

Answer 6

TIM
TOM

Question 7

where do all proteins originate?

Answer 7

on ribosomes in the cytosol (except some mitochondrial proteins).

Question 8

where do most proteins remain?

Answer 8

in the cytosol

Question 9

how are proteins moved to organelles?

Answer 9

using sorting signals

Question 10

what are the three types of protein transport found in cells?

Answer 10

gates
transmembrane
vesicular

Question 11

what is gated protein transport

Answer 11

moves through pores

Question 12

what is transmembrane protein transport

Answer 12

cross the membrane into the lumen of the organelle

Question 13

what is vesicular protein transport

Answer 13

membrane-enclosed transport of proteins from one organelle to another
moves through pores.

Question 14

which complex helps move proteins from the inside of the mitochondria to the inner membrane or intermembrane space?

Answer 14

OXA

Question 15

what happens with proteins that are destined for the lumen of the er?

Answer 15

• Translation is completed in the cytosol, and correctly folded protein is passed into the ER via Sec61 complex
• Translation starts in the cytosol and the growing amino chain is threaded into the ER via Sec61 complex

Question 16

what is glycosylation?

Answer 16

addition of oligosaccharides to the protein
