What is the main structure that the cell membrane is composed of?

A phospholipid bilayer

100

Which type of cellular transport uses energy?

Active Transport (requires ATP)
Active transport occurs in the cell membrane, and involves using energy to move molecules from LOW to HIGH concentration.


100

Which type of solution is this?

Hypotonic

100

What molecules can move through the cell membrane by simple diffusion?

CO2, Gases, and Water

100
How does an enzyme act as a catalyst?

It speeds up chemical reactions

200

What is the channel protein's function?

It lets molecules in and out of the cell

200
What are the two types of transports?
Passive and Active Transport
200
Which type of transport is osmosis?
Passive Transport
200

What is diffusion?

Diffusion is when molecules move from high to low concentration.

200

What type of macromolecule is an enzyme?

PROTEIN

300
What's the difference between hydrophilic and hydrophobic?
Hydrophilic means its attracted to water and hydrophobic means repelled by water
300
What are the three types of passive transport?
Diffusion, Facilitated diffusion, and Osmosis
300

Hypertonic

300

What is passive transport?

Passive transport is moving molecules across the cell membrane without using energy, from high to low concentration.

300

Name two factors that can impact the effectiveness of enzyme function in the body.

temperature & pH level

400

What is the main function of the cell membrane?

It acts as a protective, selectively permeable boundary for the cell, regulating the entry of nutrients, exit of waste, and maintaining a stable internal environment (homeostasis). 

400

Osmosis is the movement of _____________ through a membrane.

WATER

400
What is osmosis?
Water that moves from a high to a low concentration
400

What is this structure showing? http://hyperphysics.phy-astr.gsu.edu/hbase/biology/imgbio/celmem.gif

The Cell Membrane

400

Define activation energy.

The amount of energy it takes for a chemical reaction to occur-- enzymes help to lower activation energy.

500
What are the three important components in the cell membrane?
Cholesterol, Protein, and Phospholipids
500

What is this an example of? http://3.bp.blogspot.com/_Zvyh1feziJU/TSKOhpAYbmI/AAAAAAAAAFE/IOZFP-M-V3c/s320/diffusion.gif

Passive Transport

500

Which solution has equal amounts of water inside and outside the cell?

Isotonic

500

Explain Facilitated diffusion

When protein molecules in the cell membrane help move larger molecules across

500

Why is having enzymes in our body so important?

Our body needs enzymes to help the chemical reactions occur quicker. Enzymes help our bodies work effectively/to its greatest potential.
