Can anyone help me with this question? how do enzymes affect activation energy in a chemical reaction

Enzymes lower the activation energy that is needed, making reactions happen at a lower temperature that they could without the enzyme. This speeds up the rate of reaction.

Explanation:

blue stars have the highest surface temp

stellar distances are usually expressed in light-years

the measure of a star's brightness is called magnitude

hope this !

both male and female gametes are produced by meiosis of the germ cells. therefore, both male and female gametes are haploid. one male and one female gamete unite during the fertilization to form the diploid zygote. in seed bearing plants, pollen grain is the male gametophyte, which produces sperm cells.
