Building Blocks
Every organic compound contains this element.
Carbon
This organic compound provides a quick source of energy.
Cholesterol and waxes are examples of these.
Lipids
These compounds store genetic information.
nucleic acids
Enzymes speed up these chemical processes.
reactions
These are the building blocks of proteins.
amino acids
Fruits and grains are common food sources of these compounds.
carbohydrate
A lipid with double bonds is called this type of fat.
unsaturated fat
Scientists searching for possible life may look for molecules containing this element.
carbon
Enzymes reduce this energy barrier needed to start a reaction.
activation energy
These are the building blocks of carbohydrates.
Monosaccharides
Carbohydrates contain carbon, hydrogen, and this third element.
oxygen
Lipids do not mix well with this substance.
water
A chain of folded amino acids describes this type of molecule.
proteins
This enzyme acts on lactose.
lactase
Lactose is made of two smaller sugar units, so it is this type of carbohydrate.
Disaccharide
The ratio of carbon to hydrogen to oxygen in many carbohydrates is this.
1:2:1
In the human body, fibrinogen is necessary for sealing cuts and stopping the loss of blood. Since
fibrinogen is made of chains of amino acids, it is an example of which type of organic molecule?
Protein
A sugar-phosphate backbone and nitrogen bases are features of this type of molecule.
nucleic acid
Catalase breaks hydrogen peroxide into these two products.
water and oxygen
Breaking down stored starch produces these simple sugars.
Monosaccharides
Plants store energy in this carbohydrate.
starch
A protein’s function depends heavily on this feature of the molecule.
