Animal cells Flashcards
1
Q
mitochondria - structure
A
- double membrane
2
Q
mitochondria - function
A
- aerobic resperation
- forms ATP
- ATP used as a source of energy for: growth, cell division, metabolic reactions ect.
3
Q
Rough Endoplasmic Reticulum (RER) - Structure
A
- composed of cisternae covered in ribosomes
4
Q
Rough Endoplasmic Reticulum (RER) - function
A
- synthesis of protines
- packages proteins into vesicles and transports them to other parts of the cell - eg Golgi apparatus
5
Q
Ribosomes - function
A
- where amino acids are bonded together to form proteins - protein synthesis
6
Q
centrioles - structure
A
- small tubes of protein fibers
7
Q
Centrioles - function
A
- form spindle fibers in cell division
8
Q
Golgi apparatus/body- structure
A
- stack of membrane bound flattened sacs
9
Q
Golgi apparatus/body- function
A
- modifies the proteins and packages them into vesicles to be transported
10
Q
plasma Membrane- structure
A
- phospholipid bilayer with embedded proteins
11
Q
Plasma Membrane- function
A
- partially permeable and regulates transport in and out of cells
- separates cell contense from outside environment
12
Q
Smooth Endoplasmic Reticulum (SER) - structure
A
- composed of cisternae
13
Q
Smooth Endoplasmic Reticulum (SER) - function
A
- Makes: steroid hormones
- regulates: calcium ion concentration
- processes + metabolizes: toxins/ drugs/ alcohol in liver cells
14
Q
Nucleolus - structure
A
- inside the nucleus
15
Q
Neucleolus - function
A
- makes RNA + ribosomes
