A&P Cell Organelle and Transport

Cell Organelles 1

1

The organelle that protects the cell and controls movement in and out of the cell

cell membrane

2

The organelle that initiates protein production

nucleus

3

The organelle is used for the storage of proteins or to contain solids or liquids engulfed by the cell

vesicle

4

The organelle used to transport materials around the cell

endoplasmic reticulum

5

Synthesizes lipids and hormones.

Smooth ER

Cell Organelles 2

1

Does respiration- converts glucose to ATP

mitochondria

2

Assembles proteins

ribosome, (with the help of mRNA and tRNA) and made up of rRNA 

3

Modifies, packages, and ships proteins 

Golgi apparatus

4

Cleans up the cell and gets rid of unwanted waste

lysosome

5

Detoxifies toxins and processes free radicals

peroxisome 

Free radicals are unstable atoms (extra e-) naturally formed during metabolism or by exposure to environmental toxins. Excess free radicals can damage cells, cause diseases, and accelerate aging.

Transport 1

1

Molecules that can diffuse directly through the cell membrane

small, non-polar

2

Molecules that use protein channels to enter the cell

small polar molecules

3

The type of transport that requires an input of energy (ATP)

active transport

4

if a cell is in a hypertonic solution, which way will water diffuse? And what is that called?

out of the cell

osmosis

5

The process of engulfing large molecules into the cell

endocytosis

Transport 2

1

Give an example of a small non-polar molecule

oxygen or carbon dioxide

2

Give an example of a small polar molecule

water

3

This type of transport allows small non-polar molecule to diffuse through the membrane

simple diffusion

4

This type of transport allows polar molecules through protein channels in the membrane

facilitated diffusion

5

This is the only type of transport that requires energy and moves Na/K

sodium-potassium pump

Cell Membrane

1

The heads of the membrane are...

The tails are ...

hydrophilic

hydrophobic

2

this transport glucose across the membrane. is it a protein channel or carrier protein?

GLUT, carrier protein

3

this the the protein that allows water to move across the cell membrane. is it a protein channel or carrier protein?

aquaporin

4

the cell membrane is made up of ____ and has ____ throughout to give it flexibility

phospholipids, cholesterol

5

If the cell membrane no longer functions or has a hole, this happens to the cell...

cell death, apoptosis
