Energy bearing compound
Same enzyme doing basically the same reaction but in a different way
The folded bits in the mitochondria
What is cAMP?

Using RNA as a template for making protein
Dynein that is used for cilliary and flagellar motion

Shut down mitosis
What enzymes act upon
A flattened extension of a cell, by which it moves over or adheres to a surface

Portion that is connected to filament
Made of actin and actin-binding proteins, responsible for cell shape, contraction, motility, and cellular transport
A substance can be called this if you can put one wavelength in and get a different wavelength out

Any device that changes some measurable quantity into another measurable quantity
Proteins that exchange solutes
Growth by the addition of monomers
