Answer:
d. Glucose has the right shape and charge to cause hexokinase to undergo a structural change needed for catalysis, whereas water does not.
Explanation:
<u>d is the correct option</u>. It explains the <u>reaction specificity of hexokinase</u> during glycolysis. Glycolysis is the metabolic pathway in which glucose is converted to pyruvate to generate a high energy molecule in the form of ATP and NADH.
In the first step of glycolysis, glucose (6-carbon ring) is catalyzed to glucose-6-phosphate by Hexokinase enzyme using Mg-adenosine triphosphate (Mg-ATP) as a source of phosphate. <u>Hexokinase demonstrates conformational change on binding site in glucose</u>. Precisely, it brings C6-OH group of glucose and Mg-ATP close and binds together at the active site. This bond excludes water (H2O) from the active site. The active site has the capability to bind two ligands, glucose, and glucose-6-phosphate. When glucose binds, hexokinase goes through an induced-fit conformational change that prevents the hydrolysis of ATP.
<em>Final impression: </em>Such a catalysis is specified to hexokinase, and cannot be done by any other molecule. Glucose has the right shape and charge to cause hexokinase to undergo a structural change needed for catalysis, whereas other molecule is not suitable for this reaction.

In English: Airplanes are pressurized to ensure that there is enough oxygen in the air we are breathing when we are at such great heights. This is why when you are on a flight, you (hopefully) don't pass out. Rather, the worst you get is your ears popping. Maybe a headache.
Google Translate Indonesian translation: Pesawat terbang diberi tekanan untuk memastikan bahwa ada cukup oksigen di udara yang kita hirup ketika kita berada di ketinggian yang luar biasa. Inilah sebabnya mengapa ketika Anda sedang dalam penerbangan, Anda (semoga) tidak pingsan. Sebaliknya, hal terburuk yang Anda dapatkan adalah telinga Anda muncul. Mungkin sakit kepala. Saya taruh ini di Google Translate jadi saya harap Anda bisa mengerti.
