Answer:
<h2>Protein</h2>
Explanation:
1. Large number of ribosomes are present in the cells and they play major role in the synthesis of protein.
2. The protein synthesis occurs according the sequence of codons in the mRNA, the tRNA brings amino acids to the to the ribosomses and a peptide bond is formed between two amino acids and finally protein is formed.
3. There are two sub-units of ribososme, named small sub-unit and large sub-unit which synthesis protein.

Albedo is the ability of a surface to reflect sunlight. The word albedo means whiteness in Latin (albus means white) - it means that objects which are colored lighter tend to be lower, and on the other hand, objects which are darker tend to be higher.
Activation energy is the amount of energy required in a chemical reaction.
Enzymes lowers the activation energy by increasing the rate of reaction.
The energy required for a reaction to start is called activation energy. Enzymes are proteins that lower the activation energy of a reaction. In doing this, enzymes increase the rate of a reaction, helping it to occur faster. However, enzymes are not consumed in a reaction; they simply help it to occur.
