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.
Answer:
d
Explanation:
it is a compound chemical made up of 24 atoms
Plant and animal cells both have nucleus
B) Golgi bodies on because they can be both rough and smooth depending on how many ribosomes there is that is a way to identify which one is rough and which one is smooth the one with the least ribosomes is the smooth Golgi bodies hope this helped
Answer:
Bison have limited type of natural predators.
Explanation:
A Bison is a land animal which has a similar appearance to that of a buffalo. They are known to be fast,agile and strong.
A prairie habitat is an ecosystem that is considered part of the temperate grasslands, savannas, and shrublands biome by ecologists due to the similarities in the temperate climates, moderate rainfall and composition of grasses, herbs, and shrubs instead of trees as the main and common vegetation type.
This habitat consists of animals and reptiles such as bison, coyote, antelope, badger, elk, prairie dog, otters, foxes,lizards.
This represents a limited number of predators for the Bison
