Effectus [21]

Answer: D. Digestion increases as the volume of the enzyme increases.

Explanation:

Enzymes speed up reactions by reducing the activation time of a reaction. If there are more enzymes therefore, the reaction will move faster.

Pepsin is an enzyme that prefers acidic conditions so it can work with dilute HCL. It can also work in temperatures of 40 °C without getting denatured. As more Pepsin is added therefore, the reaction will move faster and digestion will increase.

slava [35]

When a cat drops from a tree to the ground, the cat is transforming chemical energy attained from the food into kinetic energy. The later energy is used by the living species when they are performing locomotion.  

When a cat feeds on a mouse, the mouse will undergo through the process of digestion resulting in the formation of chemical energy. Thus, the food consumed by the cat will get transformed into chemical energy that can be utilized by the cat to perform its usual activities.

ANTONII [103]
I believe proteins are synthesized from amino acids during synthesis reactions.
Protein synthesis starts with transcription of mRNA from a DNA gene in the nucleus.Various types of RNA may have been synthesized using the appropriate DNA. The RNAs migrate from the nucleus to the cytoplasm where the process of translation takes place. During the process the mRNA with the codons (three nucleotide bases that code for a specific amino acids) is interpreted by the anticodons in the tRNA , thus forming amino acids with together forms polypeptides and then proteins are formed.
