Answer:

D. Catalysts speed up the rate of reactions by lowering the amount of energy required for the reaction to proceed.

Explanation:

A catalyst is a substance that:

  • speeds up the rate of a reaction .
  • does not alter the products of the reaction .
  • is unchanged chemically and in mass at the end of the reaction.

<em>A catalyst provides an alternative reaction pathway that has a lower activation energy than the uncatalyzed reaction. </em>

<em></em>

The figure shows how the energy of the reactants and products change during a reaction.

In humans, infections by fungi and protists are usually more difficult to treat than bacteria infections. Suggest an explanation
Basile [38]
<span>Fungal diseases are difficult to treat mainly because they are eukaryotic organisms just like us humans, and therefore have less differences for drugs to target without harming the human body as well. Most antibiotics target e.g. the peptidoglycan layer in the bacterial (a prokaryote) cell wall, which is a safe target since eukaryotic cells do not have equivalent structures. Similarly many differences in metabolic pathways between humans and prokaryotes is often targeted by antibiotics, but metabolism of fungi and humans is much more uniform, and hence it is difficult to exclusively target the fungi only.

HOPE THIS HELPS!
