Compact fluorescent bulbs are a more efficient way to provide electrical light within homes and other buildings. These bulbs are one of the easiest ways to save money. According to GE, compact flourescent bulbs, or CFLs for short, use 70% less energy than a traditional, incandescent bulb and last up to 10 times longer than a standard incandescent bulb. As society pushes for improved efficiency, compact flourescent bulbs need to be carefully examined. Although these bulbs are more efficient, there are many problems with compact fluorescent bulbs.
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:
Plants are called producers. This is because they produce their own food! They do this by using light energy from the Sun, carbon dioxide from the air and water from the soil to produce food - in the form of glucouse/sugar.
