Biology Chapter 1

elements

Atom

sub-atomic particles - charges and approximate masses

ions

isotopes

chemical bonds

examples (3)

number of covalent bonds that C, N, O, H can make

chemical reaction

hydrolysis

function

dehydration synthesis

function

molecules

catalyst

enzyme

activation energy

substrate

pH what does it measure?

How much acid or base does each number represent?

compounds

inorganic - definition and examples

organic - definition and the four major types, for each type know:

calories

monomer/ sub-units (ex. glucose)

polymers/ large forms (ex. glycogen)

know some functions for all four organic compound types.

Since protein was quite involved I will mention some items of interest:

Six types/categories of protein.

What determines their functions, shape etc.

What can change these characteristics?
