The answer is that Both aid in the expansion and relaxation of lungs. Diaphragm and the rib muscles are vital in the breathing process. During inhalation the intercostal muscles contract, expanding the ribcage, the diaphragm contracts, pulling downwards to increase the volume of the chest, pressure inside the chest is lowered and air is sucked into the lungs. During exhalation the intercostal muscles relax, the ribcage drops inward and downwards, the diaphragm relaxes, moving back upwards, decreasing the volume of the chest, the pressure inside the chest increases and air is forced out.
Coal is made up of carbon, so burning coal releases carbon
Answer: Option E) None of the above is true; this enzyme could bind none of these.
Explanation:
Lactose is a dissacharide composed of glucose and galactose. Hence, the enzyme lactase break down lactose into its simple sugar constituents.
However, lactase cannot bind nor break down amino acids, starch (with only glucose units) or sucrose (with two glucose units) because their constituent molecules differ markedly from that of lactose.
Thus, the enzyme lactase could bind with none of the options provided except lactose
