cellular transport

Question 1

Cell Membrane (Plasma Membrane)

Answer 1

Structure: Made up of a phospholipid bilayer and contains many proteins (Integral, peripheral, channel, glycoproteins, and steroids (Cholesterol)
Function: maintains homeostasis through balancing the pH, temperature, glucose (sugar intake), and water balance

Question 2

Passive Transport

Answer 2

A process that does not require energy to move molecules from a HIGH to LOW concentration

Question 3

Active Transport

Answer 3

the movement of molecules from LOW to HIGH concentration.
Energy is required as molecules must be pumped against the concentration gradient.

Question 4

Facilitated Diffusion

Answer 4

requires the help of carrier and channel proteins
These particles move from an area of high concentration to an area of low concentration.

Question 5

Simple Diffusion

Answer 5

the movement of small particles across the cell membrane like the cell membrane until homeostasis is reached.

Question 6

Osmosis

Answer 6

the movement of water through a selectively permeable membrane like the cell membrane
Water moves across the cell membrane from an area of high concentration to an area of low concentration.
