A meshwork of macromolecules outside the plasma membrane of animals cells. Provides support and anchorage and is rich in collagen. Plants contain the following organelles. Phospholipids are amphipathic. Enzymes raise the activation energy of a chemical reaction.
Enzymes can speed up chemical reactions by distorting chemical bonds.
Enzymes alter the D G value of a chemical reaction. Enzymes are inorganic catalysts. All of the above are correct. An example of a coupled reaction is one in which the hydrolysis of ATP is linked with an endergonic reaction. Above this temperature the substrates slow their random molecular movement.
