Starch is a polymer composed of glucose units as monomers. Hydrolysis reaction can break down large molecules into smaller ones.

  • Hydrolysis is a type of chemical reaction in which a water (H2O) molecule is used to break down large molecules into smaller ones.

  • Starch is a complex polysaccharide composed of more than six (6) glucose molecules linked by alpha-glycosidic bonds.

  • Glycosidic bonds can be hydrolyzed by specific enzymes known as glycosidases.

  • A starch molecule composed of 300 glucose molecules contains 299 alpha-glycosidic bonds.

  • In consequence, in this case, 299 water (H2O) molecules are required to completely hydrolyze the amylose starch polymer into glucose monomers.

Use a Punnett's squares to show a monohybrid cross between pure breeding parents of tall (T) and dwarf (t) pea plants.
marusya05 [52]

Answer/Explanation:

True breeding means the parents have two copies of the same allele (two of the same letter)

That means the monohybrid cross is TT x tt

<u>       T            T </u>

t      Tt          Tt

t      Tt          Tt

All the offspring have one copy of each and are Tt. Tall is dominant to dwa rf. So all the offspring will be tall.

What is the role of light and chlorophyll in photosynthesis?
schepotkina [342]

Answer:

Chlorophyll's job in a plant is to absorb light—usually sunlight. The energy absorbed from light is transferred to two kinds of energy-storing molecules. Through photosynthesis, the plant uses the stored energy to convert carbon dioxide (absorbed from the air) and water into glucose, a type of sugar.
