Chapter 3: Active And Passive Transport

Question 1

Active Transport

Answer 1

The process of transferring substances in and out of the cell, USING ENERGY.

Question 2

When is active transport moving energy?

Answer 2

Against the concentration gradient

Question 3

Define concentration gradient

Answer 3

Concentration gradient is when the concentration of particles is higher in one area than another. Thus in simple terms uneven particles.

Question 4

Passive Transport

Answer 4

Can be described as the process of moving substances in and out WITHOUT USEING ENERGY.

Question 5

What is another term that can be used to describe passive transport?

Answer 5

Passive diffusion

Question 6

What type of transport does not require energy

Answer 6

Passive transport

Question 7

The ability of the human body to stay in balance or sameness is?

Answer 7

Homeostasis

Question 8

Membrane

Answer 8

The outer job boundary of all cells, it’s job is to move things in and out of the cell.

Question 9

Simple diffusion

Answer 9

The movement of particles from high to low concentration without a protein channel.

Question 10

Endocytosis

Answer 10

This is used when a substance can not be brought into a cell using passive or active transport.

The membrane fuses around the substance (engulfs) and creates a vesicle (vacuole) to bring the substance into the cell.

Question 11

Exocytosis

Answer 11

Allows materials stored in vesicles and vacuoles to exit the cell.

Question 12

Facilitated Transport

Answer 12

Uses a protein channel

Movement down the concentration gradient

Question 13

What are the major 3 things that considered during active transport?

Answer 13

Diffusion

Osmosis

Movement down the concentration gradient
