1

3 Parts of signal transduction

Reception, transduction and response

2

What is the cell wall composed of

Primarily peptidoglycan

3

What is the nucleoid?

Functional compartment in prokaryotic cells, centrally located and contains the circular chromosome and small DNA plasmids

4

What are inclusion bodies?

Compartments of prokaryotic cells that are granules containing organic or inorganic compounds

5

What are pili?

For attachment and sex on prokaryotes

6

What is the Edocytic Cycle for?

For recycling and remodeling of membranes

7

Bending in cilia and flagella occurs via which molecular motor, and are powered by what?

Dynein and ATP

8

Plasma membranes can be involved in what two metabolic processes?

- photosynthesis
- respiration

9

What does the endomembrane system do?

Increases surface area for chemical reactions

10

What is glycocalyx?

Extracellular polymeric material (eg. glycoproteins).

11

What organelle are lipids biosynthesized in?

The smooth ER

12

Where do vesicles originate from? (3 sources)

- ER
- Golgi
- Via endocytosis

13

What are the enzymes found in lysosomes called?

Acid hydrolases. They degrade debris in cells and are involved in autophagy

14

True or false (for each individually)?
1. Mitochondria have their own DNA
2. Mitochondria have their own ribosomes

1. True
2. True

15

What is a peroxisome?

A small organelle containing oxidative enzymes. Detoxifies peroxides (eg. H2O2)

16

What are plastids? What are two types of plastids?

Organelles found only in plants algae and some protists.

Two Types: leucoplasts and chromoplasts

Chloroplasts are chromoplasts specialized for photosynthesis
