One of the roles of blood is to transport nutrients around the body and deliver molecules such as sugars and lipids to cells. A scientist makes the observation that since blood is composed of water, sugars tend to dissolve, while lipids aggregate. Which of the following claims would be the most useful way for scientists to explain this phenomenon? Smaller and simpler molecules such as sugars tend to dissolve, while larger and complex molecules such as lipids aggregate out. When water is heated, it takes less heat to dissolve sugars than it does to dissolve lipids. Water molecules stay close together as a result of adhesion, while lipids aggregate out as result of cohesion. Water dissolves some molecules while causing the aggregation of others because of hydrophobic and hydrophilic interactions.

Lactase is essential for digesting lactose in milk. this enzyme is specific for this sugar. why? molecules and active sites vary in size; only properly sized molecules can fit. there is a precise compatibility between the active site and the lactose molecule. specificity refers to the action of the enzyme, such as hydrolysis, and relatively few molecules can be hydrolyzed. reaction-specific enzymes assume a fit by folding around the most numerous substrate molecules.
