Cells at work-cell metabolism
All the chemical reactions occurring in all living organisms.
Chemical reaction that break down large organic molecules into smaller ones.
The process of combining small molecules to make larger ones.
Also know as synthesis
Large molecules that always contain the element carbon
Not containing carbon (e.g. water, oxygen) or having small molecules (e.g. carbon dioxide)
Are simple sugars or single-unit sugars; examples are glucose, fructose and galactose
Carbohydrates always contain carbon, hydrogen and oxygen.
Two simple sugars joined together; examples are sucrose, maltose and glactose
Large numbers of simple sugars joined together; examples are glycogen, cellulose and starch
Proteins always contain carbon, hydrogen, oxygen and nitrogen, and often sulfur and phosphorous
They are made up of large numbers of smaller molecules called amino acids
Contains carbon, hydrogen and oxygen, but much less oxygen than carbohydrates.
Examples of lipids are: fats, stored o=in the body as energy reserves; phospholipids, important in cell membrane; steroids, including cholesterol and the sex hormones
