Question

A biologist wants to prevent the bonding of enzymes to the substrate in his test solution. What should he do?

Answer 1

what do u think?

Answer 2

A.Add a vitamin solution
B. Add a zinc solution
C.Add an inhibitor solution
D.Add a co-factor solution

Answer 3

I was thinking C but was unsure..

Answer 4

Bingo

Answer 5

YAY! thank you! could you double check the rest of my Questions and answers please?:)

Answer 6

Using competitive or non competitive inhibitors would prevent/slow down enzyme substrate complex
okay)

Answer 7

Which component is required for the activation of some enzymes?
A. Presence of a co-factor
B.Basic pH levels in the substrate
C.Higher enzyme concentration
D.Lower temperature in the substrate
I was thinking A

Answer 8

Jack consumes two slices of pizza and drinks two large glasses of soda. Half an hour later, he complains of a stomachache. What is the most likely reason for Jack's upset stomach?
A.Soda and lactose from the cheese combined and slowed enzyme activity.
B.Soda mixed with the pizza sauce and sped up digestive enzyme activity.
C.Soda raised the pH in his stomach and sped up digestive enzyme activity.
D.Soda lowered the pH in his stomach and slowed digestive enzyme activity.
I think D for this one.

Answer 9

yup you are right with the first one

Answer 10

A beverage company advertises a new iced drink that contains important enzymes to help with digestion. What is an accurate conclusion about their claim?
A.The drink contains enzymes but they are inactive.
B.The claim is false because enzymes don't help with digestion.
C.The enzymes in the drink will increase digestion.
D.The drink probably contains very few enzymes.
I was stuck between a and d for this one..

Answer 11

i agree that its D in the previous q

Answer 12

hmmm this one is kinda tricky one

Answer 13

4. Which statement explains why the induced fit model is a more accurate description of enzyme/substrate bonding than the lock and key model?
A.Enzymes have active sites that fit most substrates.
B.Enzymes do not need active sites to bond to substrates.
C.Enzymes have rigid active sites with flexible sites for co-factors.
D.Enzymes do have flexible active sites that mold to substrates.
I was thinking A for this one..

Answer 14

I thought so as well for number 3

Answer 15

but think of it this way
what does enzyme help with>?

Answer 16

5.Which factor increases the rate of a chemical reaction?
A.An inhibitor
B.A co-factor
C.Decreased substrate
D. Cold temperature
I think this B because i believe D slows the reaction.

Answer 17

it helps with digestion right?

Answer 18

yes :) so thinking of that choose the answer that best fits
they are producing a drink that contains enzymes - what is it gonna do then? what effect is it gonna give?

Answer 19

It will increase digestion?

Answer 20

Bingo :)

Answer 21

question 4 - think about it again

Answer 22

now that i re read 5 i think it may be a inhibitor..

Answer 23

http://en.wikipedia.org/wiki/Enzyme
read the fist paragraph

Answer 24

Maybe C for number 4? since they do have active sites but do they really need them to bond with substrate?

Answer 25

Bingo :) they have rigid active sites along with a flexible site for those co factors :)

Answer 26

5- which one do u think is 'activating' the process and u can expect increase in rate of reaction?

Answer 27

an inhibitor because wouldnt that increase it?

Answer 28

Inhibitor- inhibits the action of enzyme- so decrease the rate of reaction

Answer 29

For #4 it's actually D since the induced fit model explains the flexibility of the substrate in being able to change shape rather than just fitting into one area like the lock and key model depicts. :)
