Answer 10

The area on an enzyme where a molecule other than the substrate can attach is called an:
Answer

active site

allosteric site

anabolic site

inactive site

*allosteric site

Answer 11

If an enzyme is the subject of allosteric interaction, which of these has happened?
Answer

the allosteric inhibitor has bound to the active site of the enzyme

the allosteric inhibitor has competed with the regular substrate

the allosteric inhibitor has bound to the allosteric site on the enzyme

none of these

*the allosteric inhibitor has bound to the allosteric site on the enzyme

Answer 16

Hello my friend @LoverofWords Here is another challenge for us. Are you ready? Let's go...I will waiting for your good news

Answer 17

Thank you for your help! :)

Answer 18

These all look correct to me.

Answer 19

Thank you @buckycap. Really? There's no mistakes? Are you sure. Btw...have a nice day.

Answer 20

I don't think so but I will double check for you

Answer 21

Thank you...please double check it for me. I will really appreciate it...:)

Answer 22

Oh, I'm sorry the first ones wrong. I should have seen it before. Also the difference between ATP and ADP is actually B and C

Answer 23

I'm not sure about the last one. Can there be multiple answers?

Answer 24

oh...ok...I see :)

Answer 25

No. You must choose only one

Answer 26

Ok then everything else is correct :)

Answer 27

Oxidation would be losing an electron, and reduction would be gaining.

Answer 28

Okie...:)

Answer 29

Thanks for taking your time answering my questions.

Answer 30

Are you done with this now? :)

Answer 31

Hello! Welcome back! No, no I still need your help to check my answers.

Answer 32

@LoverofWords

Answer 33

Everything looks right to me :)

Answer 34

Really? You mean what I have done is all correct. No wrong answers? Then, why the other friend said that some of my questions were wrong???

Answer 35

What is the difference between ATP and ADP?
Answer

ATP is a lower energy form of ADP

ATP is a higher energy form of ADP

ATP has one more phosphate group than ADP

both b and c are correct

*For this question, I chose ATP has one more phosphate group than ADP. But the other friend told me that it should be both b and c are correct. What do you think?

Answer 36

The formation of ATP from ADP is what kind of reaction?
Answer

coupled

endergonic

exergonic

reversible

*This one I chose B. What do you think?

Answer 37

these last two are right.
