Flashcards in Chapter 3 Part 2 Deck (25):
1

Determines cells shape and organizes cellular contents

Cytoskeleton

2

Include the microfilaments intermediate filaments and microfiber

Filaments

3

Short hair like projections at cell surface moves fluids along cell

Cilia

4

Located in sperm cell

Flagella

5

Produce protein for inside use

Free ribosomes

6

Located on rough ER produce proteins for outside use

Membrane bound ribosomes

7

1.rough ER 2.smooth ER detoxifies drugs and amounts increase during drug tolerance

Endoplasmic reticulum

8

Sorts packages and transports proteins received from rough ER

Golgi Complex

9

Formed by Golgi complex and contains digestive enzymes-digest worn out organelles by autophagy and can destroy entire cell by autolysis

Lysosomes

10

Produces most of the cells ATP -abundant in active cells -self replicate -outer and inner folds increase surface area

Mitochondria "powerhouse"

11

Is the central cavity

Matrix

12

Contains chromosomes (DNA) that controls cells activities

Nucleus

13

Encloses nucleus

Nuclear envelope

14

Located in nucleus; produces ribosomes

Nucleolus

15

Contains 46 chromosomes

Human somatic body cells

16

DNA segments

Genes

17

Equal to the total number of genes in a cell; about 30,000

Human genome

18

May consist of a single or identical double strands

Chromosomes (DNA)

19

Are chromosomes in a non dividing cell

Chromatin

20

DNA contains instructions for producing proteins , 2 steps

Protein synthesis

21

1.information contained in a specific region of DNA in transcribed (copied) to mRNA 2.mRNA (messenger) is translated (read) into cytoplasm into a specific sequence of amino acids to form a new protein

Protein synthesis

22

Occurs in nucleus

Transcription

23

Starts transcription

Promoter gene

24

Stops transcription

Terminator gene

25

2 types cytoskeleton,filament

Organelles
