Cell Functions and Intro Lessons to Marine Biology

What is the difference between an element and a compound?

Most chemical reactions within cells could not take place without

What are the four important groups of organic compounds in living things?

Provides energy for the cell and are important components of some cell parts.

• Proteins

• Lipids

• Carbohydrates

• Nucleic acids

Contains the instructions that cells need to carry out all the functions of life.

• Proteins

• Lipids

• Carbohydrates

• Nucleic acids

Enzymes that perform important functions in the chemical reactions that take place in cells belong to this group.

• Proteins

• Lipids

• Carbohydrates

• Nucleic acids

Function as an energy source and make up most of the cell membrane.

• Proteins

• Lipids

• Carbohydrates

• Nucleic acids

Movement across the cell membrane from an area of high solute concentration to an area of low solute concentration.

• Diffusion

• Osmosis

• Active transport

• Passive transport

Involves movement from a dilute solution to a concentrated solution—against a concentration gradient and requiring energy from respiration.

• Diffusion

• Osmosis

• Active transport

• Passive transport

A passive process that involves the movement of water across a semi-permeable membrane—from a dilute solution to a concentrated solution.

• Diffusion

• Osmosis

• Active transport
