<h2>Answer:</h2>
Option B is correct.
B. In an exothermic reaction, excess energy is released as heat.
<h2>Explanation:</h2>
An exothermic reaction is a chemical reaction that releases energy by light or heat. It is the opposite of an endothermic reaction. Expressed in a chemical equation: reactants → products + energy. Exothermic Reaction means "exo" meaning releases and "thermic" means heat.
Answer:
C.
Explanation:
In mRNA, there isn't a Thymine nitrogen base. There is a "new" nitrogen base called Uracil, which takes its place. So in transcription, A=U and C=G.
The reaction shown in the question is an inversion reaction.
The conversion of maltose to glucose is an inversion reaction. An inversion reaction is said to have occurred when the atoms and groups in a molecule are rearranged. The numbers and type of each atom in a molecule remains the same.
The reaction; Maltose +A -> Glucose + B is an example of an inversion reaction. The missing items A and B are both the catalyst maltase.
