Protein molecules arranged in two layers with polar areas forming the outside of the membrane.
Two layers of lipids organized with the nonpolar tails forming the interior of the membrane.
Lipid molecules positioned between two carbohydrate layers.
Protein molecules with polar and nonpolar tails.
Tomatoes need sunlight to ripen.
Humidity accelerates the ripening process.
Low temperatures reduce the action of ripening enzymes.
Enzymes produced by bacteria inhibit ripening.
Different enzymes are synthesized in specific areas of the cytoplasm.
Most enzymes can catalyze many different reactions.
An enzyme binds to a specific substrate (reactant) for the reaction catalyzed.
Enzymes are transported to specific substrates (reactants) by ribosomes.
Diluting with water
Are much smaller.
Have permeable membranes.
Have a higher rate of reproduction.
