Hi I really need to know this I've asked a couple times but haven't gotten an answer yet.

In the reaction X + Y ® Z, Z is the
A) substrate.
B) product.
C) enzyme.
D) carbon molecule.

Assuming you meant an arrow instead of a "Reserved" sign, it should be B, Product. The substrate is something being acted upon in a reaction (I'm assuming this is for a biology/biochemistry class, so in that case the substrate is what's being acted on by the enzyme). An enzyme is a complex protein that acts on another chemical (the substrate). So X or Y could the enzyme or substrate. Given the general form of the equation, they could be any molecules, so 'carbon molecule' doesn't make sense. Finally, when two things react together they PRODUCE the PRODUCT.

K thank you very much and actually that's how the question was written which threw me off completely. (I think it stands for chemical reaction, it was random to see though). Thank you for your help though. I understand it much better now!

To determine which option is correct in the given reaction X + Y ® Z, it is important to understand the roles of each component in a chemical reaction.

In a chemical reaction, substrates are the reactants that undergo a chemical change to form products. Products, on the other hand, are the substances that are formed as a result of the chemical reaction. Enzymes, on the other hand, are biological catalysts that facilitate chemical reactions by speeding up the conversion of substrates into products.

In this case, Z is the product formed in the reaction. Therefore, the correct answer is:

B) product.

To arrive at this conclusion, you can analyze the reaction and identify the components involved. The reactants X and Y are undergoing a chemical change, and the resulting substance is Z. Thus, Z is the product in this reaction.
