Functions are energy storage, receptors, structure of plant cell wall What is an example of a lipids and its associated functions? correct answers Example: cholesterol; Functions: membrane, structure, energy storage What is an example of a nucleic acids and its associated functions? correct answers Example is RNA, it functions: information storage and transfer What is an example of a proteins and its associated functions? correct answers Example is enzymes, its functions: structure, receptors, transport True or False A solvent is the dissolved matter in a solution correct answers False When microorganisms (usually yeast) undergo fermentation, they obtain their energy by: correct answers Anaerobic respiration The enzyme maltase catalyzes the break down of maltose into glucose. A technician added maltase to a solution of maltose to be incubated at 37°C. Samples were taken from the reaction tube every five minutes over the course of one hour, to measure the glucose concentration. After an hour, the technician noticed the water bath failed to reach 37°C (it only warmed to 25°C). Which of the following is the most likely outcome of the reaction? correct answers The enzyme activity would decrease, yielding the same level of glucose over a longer time period.
