lipids - amino acids

proteins - nucleotides

carbohydrates - sugars

nucleic acids - enzymes

They produce quick energy

They are saturated with hydrogen

Helping animals conserve heat

Their compositions differ only

It rotates and enables the cells to move.

It carries molecules from one part of the cell to the other.

It acts as the cell's control center.

It controls what materials enter and leave the cell.

Prokaryote

Eukaryote

Organelle

Lysogenic Cycle

Viral Reporduction

Lytic Cycle

Capsid Cycle

They are more complex in structure and function than bacteria.

They are eukaryotic cells.

They consist of a nucleic acid surrounded by a protein coat.

They are usually not pathogenic.

Mitosis

Synthesis

Gap 2

Cytokinesis

Each chromosome makes a copy of itself.

The cell cytoplasm divides to produce two cells.

The cell prepares to divide.

The nucleus divides, so that each cell will receive a complete set of genetic information.

Enzyme

Substrate

Active Site

Product

Enzyme specificity

Changes in enzymes after reaction

Conversion of substrate into products

Release of activation energy

By providing support and structure for the cell.

By regulating the transport of materials in and out of the cell.

By manufacturing protein to provide energy for the cell.

By storing food as future energy for the cell.

Iodine cannot pass through a membrane

A semipermeable membrane will allow diffusion of selected molecules

Starch can be easily diffused through a membrane

A permeale membrane diffuses chemicals in and out of the surface.
