While studying enzyme kinetics in the lab, a scientist observed that the rate of a reaction involving enzyme amylase increased as the concentration of starch increased. with further increase in starch concentration, the amylase activity did not change. why did this happen?

a. the starch molecules did not bind to the enzyme amylase efficiently.

b. the enzyme amylase was saturated, as all its active sites were occupied by substrate starch.

c. the starch molecules were converted to product glucose as soon as they bound to enzyme amylase.

1: most common garden plants prefer loam — soils with a balance of different-sized mineral particles (approximately 40% sand, 40% silt, and 20% clay) with ample organic matter and pore space. however, some plants grow better in sandy soils, while others are well-adapted to clay soils.

2: available water capacity is the maximum amount of plant available water a soil can provide. it is an indicator of a soil's ability to retain water and make it sufficiently available for plant use. available water capacity is the water held in soil between its field capacity and permanent wilting point.

3: it is the same for all living things (plants and animals). it also includes very tiny organisms that our eyes cannot see. they are known as microorganisms, and include viruses, bacteria and fungi.
