Lecture 5

Question 1

Ribosomes

Answer 1

Build proteins during translation

Question 2

Free Ribosomes

Answer 2

Proteins stay in cell (Cytosol/Cytoplasm)

Question 3

Fixed Ribosomes

Answer 3

Secret made proteins (ER)

Question 4

Smooth ER

Answer 4

Carbohydrates and lipids

Question 5

Rough ER

Answer 5

Protein production

Question 6

Golgi Apparatus

Answer 6

Receive vesicles from rough or smooth ER and repackage the proteins, carbohydrates, lipids.
Send out transport vesicles for secretion, membrane renewal, lysosome production (breakdown bacteria).

Question 7

Cisternae

Answer 7

Part of golgi that stores the vesicles made in the ER

Question 8

Chromatin

Answer 8

Loosely coiled DNA (cells not dividing)

Question 9

Chromosomes

Answer 9

Tightly coiled DNA (cells dividing)

Question 10

Gene

Answer 10

Instruction for one protein

Question 11

mRNA

Answer 11

Messenger RNA, takes message to ribosome

Question 12

Mitosis

Answer 12

Cell division (somatic cells, twice, genetically identical)

Question 13

Cells are mostly in __________.

Answer 13

Interphase

Question 14

Meiosis

Answer 14

Cell division (sex cells, four times, random halves of original DNA)

Question 15

Protein production steps in ribosome

Answer 15

Ribosomes read mRNA, tRNA brings proper AAs from cytoplasm, protein made when sequence is done.

Question 16

Interphase

Answer 16

Reading and transcribing (proteins)

Question 17

Cell Divison Comparisons

Answer 17

WBCs>Epithelial gut cells>Skins cells>Skeletal muscle cells>Neurons

Question 18

Cell Divison needed for

Answer 18

Growth and to replace dead/dying cells

Question 19

Metastasis

Answer 19

Spread of cancer to distant locations
