tekilochka [14]

Answer:

c. A single enzyme typically reacts with many different substrates.

Explanation:

Enzymes are proteins that have catalytic activity and they are specific. This means that a single enzyme has only one specific substrate. They act as a "lock and key" complex, so one substrate activates to one enzyme.

Also, enzymes accelerate the rate of a reaction by lowering its activation energy. Finally, they can act in an aqueous environment, so the answer is c.

Explain how the terms atom, compounds, element, and molecules all relate to one another
Alex777 [14]
For starters, atoms are the basic building blocks of matter- they make up elements, molecules and compounds. Elements most often combine with other elements as compounds. Whilst molecules are particles found in both elements and compounds. I hope that wasn't too confusing, but bottom line is that they are all linked together in this way! Helpful? :)

Would you expect that anions would be physically closer to the oxygen or to the hydrogens of water molecules that surround it in
marshall27 [118]
Anions are negatively charged particles. The water molecule is a polar molecule, that means that, it is partly positive and partly negative. The oxygen atoms in the water molecules are more electronegative more than the hydrogen atoms and they draw the shared electron nearer to themselves than the hydrogen atoms; this make them to be slightly negatively charged while the hydrogen atom is slightly positively charged.
Therefore in solution, the anions would be attracted toward the hydrogen atom that is slightly positive while the cations will be attracted to oxygen atom that is slightly negative.
