The material or substance on which an enzyme acts upon is known as the substrate, they are nothing but reacting molecules and or substances that are able to ultimately be converted to product substances. By the aid of biological enzymes, that lower the energy of activation needed for a chemical reaction to proceed.
<u>Answer:</u>
Although statements are not given in the question, we could make the most possible deduction as follows:
The allele for purple flowers is dominant whereas allele for white flowers is recessive.
<u>Explanation:</u>
According to the question,
- Purple flower plant was crossed with white flower plant.
- All offsprings have purple flowers.
Here we have one possibility that both parents were homozygous but in their own traits. <u>Purple flower</u> plants were "PP" and white <u>flower plants</u> were "pp" So, the <u>first progeny</u> (direct offsprings) would have "Pp". So, as per considerations, purple is dominant allele which will mask the recessive allele thus defining the color of all offsprings as purple. However, further cross of their generation will definitely end up into purple and white flowers (3:1) but this condition is not mentioned in the statement.
