Answer :
a). Oxygen and glucose are the two reactants necessary for cellular respiration. b). When cells respire, glucose (sugar) and other reactants are used. c). It is employed in the initial phase of cellular respiration. d). None of the others are used.
a). In the process of cellular respiration, both oxygen and glucose are reactants. Carbon dioxide and water are waste products of cellular respiration, with ATP serving as its primary product.
b). The process that transforms chemical energy is known as cellular respiration, and the reactants and products involved include oxygen, glucose (sugar), carbon dioxide, and water. The reactants, glucose (sugar) and oxygen, mix during cellular respiration to create new products, carbon dioxide molecules and water molecules. In order to provide energy for other cellular functions, adenosine triphosphate (ATP) is created.
c). As the primary substrate processed during glycolysis, glucose is utilized at the very first stage of cellular respiration. Pyruvate is generated once glucose is broken down into it, and then the pyruvate molecules are changed into acetyl CoA.
d). Glucose is, in fact, the main chemical used in cellular respiration. However, additional molecules can also be used in cellular respiration to generate energy, including: Lactic acid, which the liver can convert into glucose and then use in the process known as glycolysis to generate energy.
