Answer:
a. The alpha-carbon
Explanation:
An amino acid is an organic molecule that contains a carboxyl (COOH) and a amino (NH2) group. It has a central carbon called as alpha carbon.
The carboxyl and amino groups are attached to the the alpha carbon. Apart from them, a side chain denoted by "R" is also covalently attached to it. Side chain varies in each amino acid and it imparts the unique properties to the particular amino acid.
The right answer is a. synthesis of energy-rich sugars.
With chlorophyll, green plants absorb the light energy needed to synthesize an organic chemical species, glucose C6H1206, from carbon dioxide and water vapor. Each billion tons of the carbon element C are fixed by the green plants in the form of glucose. The reaction, called photosynthesis, also produces dioxygen and helps to regenerate this chemical species necessary for the breathing of living beings.
Explanation:
when the ball rolls down a hill potential energy conversion takes place to kinetic energy. and when it starts rolling down the hill, then kinetic energy=1/2mv^2
