18 which of the following statements are correct? some enzyme-catalyzed reactions would cease completely if their enzyme is absent. a) hydrolysis of atp to amp can provide about twice as much energy as hydrolysis of atp to adp b) some activated carrier molecules can transfer both energy and a chemical group to a second c) molecule. hint: think acetyl-coa d) the rule that oxidations release energy, whereas reductions require energy input, applies to all chemical reactions, not just those that occur in living cells. e) cold-blooded animals have an energetic disadvantage because they release less heat to the environment than warm-blooded animals do. this slows their ability to make ordered macromolecules.

lesson summarykaryotypes a genome is the full set of all the genetic information that an organism carries in its dna. chromosomes arebundles of dna and protein found in the nucleus of a eukaryotic cell.

answer: the correct option is d. enzyme

lactase and carbonic anhydrase are the examples of enzymes.

lactase is an enzyme, which is present in the small intestine of mammals. it in the digestion of the disaccharide, lactose ( milk sugar) by converting it into two monosachharide, which are glucose and galactose.

carbonic anhydrase is present in the red blood cells. this enzyme plays significant role in the transport of co₂. it in the conversion of co₂ and h₂o into carbonic acid, which is then dissociated into bicarbonate ions and hydrogen ions.
