Answer:
Catalysts lower the activation energy for reactions. The lower the activation energy for a reaction, the faster the rate. Thus enzymes speed up reactions by lowering activation energy. Many enzymes change shape when substrates bind.

Answer:
It is not usually a component of eukaryotic membranes.
Explanation:
Cholesterol is responsible for modulating the fluidity of the cell membranes of eukaryotes.
It is produced in most animal cells, and its formation is substantially active in <u>liver</u> cells, where bile acids are synthesized from cholesterol.
In addition, cholesterol is the precursor of steroid hormones such as progesterone, testosterone, estradiol and cortisol.
Cholesterol (like other lipids) is <u>amphipathic</u>, meaning it has a polar head (hydrophilic) and an apolar tail (hydrophobic).
Given the above, it can be concluded that the false statement is "it is not usually a component of eukaryotic membranes".
<span>Evidence that supports this includes the lack of true tissue in sponges and the close similarity between choanocytes and choanoflagellates.</span>
