Phagocytosis, ppinocytosis and receptor mediated endocytosis
What is types of endocytosine
100

the difference in electrical charge across a cell’s membrane — the inside of the cell is usually more negative compared to the outside.

What is membrane potential

100
The movement of ions or molecules across a cell membrane into a region of higher concentration assisted by enzymes requiring energy.
What is active transport
100

spontaneous movement of particles from an area of high concentration to an area of low concentration until they are evenly spread out

What is diffusion

riya's major

what is biology?

200
If a plant cell and its surroundings are_____, there is no movement of water into the cell and the cell becomes flaccid and the plant could wilt.
What is isotonic
200
Having both hydrophilic and hydrophobic parts.
What is amphipathic
200

Having a higher osmotic pressure outside than a particular intra cellular fluid.

What is hypertonic

200

Having a lower osmotic pressure outside than a particular intracellular fluid.

Two types of transport proteins facilitate the movement of molecules or ions across membranes.
What are channel proteins and carrier proteins
300

Process where transport of a particular solute can indirectly drive the active transport of several other solutes. 

What is cotransport

300

concept where the cell membrane allows some substances to pass through but blocks others.

What is selective permeability

300

the ability of a solution to cause water to move into or out of a cell by osmosis

What is tonicity

400
Intergral membrane proteins from a larger family of major intrinsic proteins that form pores in the membrane of biological cells
What is aquaporins
400
A model that describes the structure of cell membranes . In this model a flexible layer made of lipid molecules is interspersed with large protein molecules that acts as channels through which other molecules enter and leave the cell.
What is fluid mosaic model
400
An integral membrane protein that is capable of moving protons across a biological membrane.
What is proton pump
400

he movement of substances across the cell membrane without using energy (ATP) — particles move from high to low concentration.

500

A process by which the contents of vesicle are released to the exterior through fusion of the vesicle membrane with the cell membrane

What is exocytosis

500

Passive transport of polar molecules and ions w/ help from proteins

What is facilitated diffusion.

500
The maintenance of constant osmotic pressure in the fluids of an organism by the control of water and salt concentrations
What is osmoregulation
500

the diffusion of water through a selectively permeable membrane from an area of low solute concentration to high solute concentration.

What is osmosis
