1

Basic living unit of the body

Cell

2

Cells that always replicate

Labile Cells

3

Cells that are inactive but can replicate when needed

Quiescent/Stable Cells

4

Cell that cannot replicate

Permanent Cells

5

Substances that make up the entire cell

Protoplasm

6

Components of the Protoplasm

water (70-80%), proteins (10-20%), lipids(2%), ions, carbohydrates

7

The Cell: Contains DNA, histones & chromosomes, has nucleoli

Nucleus

8

The Cell: Powerhouse of the cell

Mitochondria

9

The Cell: Involved in detoxification, lipid synthesis, converting lipid-soluble substances to water-soluble substances

Agranular/Smooth Endoplasmic Reticulum

10

The Cell: For synthesis of proteins bound for the cell membrane, lysosomes, outside of the cell

Rough Endoplasmic Reticulum

11

The Cell: For synthesis of proteins bound for the cytoplasm and mitochondria

Free-floating Ribosomes

12

The Cell: For packaging,molecular tagging and synthesis of hyaluronic acid and chondroitin sulfate

Golgi Apparatus

13

The Cell: Contains proenzymes, neurotransmittters and replenishes cell membrane components

Secretory Vesicles

14

The Cell: For regression of tissues and autolysis, suicide bags of the cell, destroys foreign bodies

Lysosomes

15

The Cell: Degrades membrane-associated proteins, not membrane-bound

Proteosomes

16

The Cell: Contains oxidases, catalases, helps in lipid synthesis and detoxification

Peroxisomes

17

Processes that happen both in the cytoplasm and the mitochondria

Heme synthesis, Urea cycle, Gluconeogenesis

18

Face of the golgi apparatus that accepts inactive proteins

Cis Face - convex

19

Face of the golgi apparatus that releases mature proteins

Trans Face - concave

20

Site of transcription and processing of rRNA

nucleolus

21

Contains its own DNA that is maternally derived and does not follow the genetic code

mitochondria

22

Exclusively Mitochondrial Processes

β-oxidation, Krebs Cycle

23

RER and SER are abundant in the

liver - other organelles are also increased

24

What are the components of prokaryotic ribosomes?

30s + 50s = 70s

25

What are the components of eukaryotic ribosomes?

40s + 60s = 80s

26

Specialized SER in the skeletal muscle

sarcoplasmic reticulum

27

Specialized SER in the neuron

Nissl substance

28

The only substance modified in the RER and not in the golgi apparatus

collagen

29

What is added to lysosome-bound proteins by the golgi apparatus?

mannose 6-phosphate (M6P)

30

Lysosomes come from which organelle?

golgi apparatus
