Answer:

B, D

Explanation:

All of the answers apply to enzymes because they are known as biological catalysts (all the features of a catalyst plus some biological things like being proteins and succumbing to high temps).  However, other catalysts are not biological, so they are not made of proteins nor adversely affected by high temps.  They are however, in their very catalytic nature, going to speed up chemical reactions and will not be used up during the reaction (they just get it going).
