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. A chemical reaction at equilibrium always has equal concentrations of substrate and product. Heat is the least efficient form of kinetic energy.
