Please help!!

** peptide bond picture is for 1 and 2**
1. In this CHEMICAL reaction, what happens to WATER?
a.water is not involved in this reaction in any way

b.water goes both "in/enters" and "out/exits" of the reaction

c.water goes "into" or "enters" the reaction

d.water comes "out of" or "exits" the reaction

2. In this METABOLIC reaction, what happens to ENERGY?
a.energy goes "into" or "enters" the reaction

b.energy is not involved in this reaction in any way

c.energy comes "out" of or "exits" the reaction

Answer:

1. d.water comes "out of" or "exits" the reaction

2. a.energy goes "into" or "enters" the reaction

3. Path A

Step-by-step explanation:

1) Peptide bond synthesis is dehydration reaction which means water is "dehydrated" meaning released when the reaction occurs.

2) Anytime we want to join things together we gotta use energy, these processes are anabolic reactions such as making sugars, proteins, lipids, in our cell. Since we are making protein here, we need to put energy into the reaction.

3) Path A is hydrophobic b/c they directly diffuse thru cell membrane to attach to intracellular receptor.

My best attempt, hope its right.
