2) Wrong type of amylase. Would expect optimum to be 7 but was 3.

2) It seems strange as Amylase is usually found in the mouth and ph 3 is very acidic. You would think that it would be more neutral/alkaline.
3) Using the same iodine for each test and by human error when you are deciding that there is no longer a colour change in the iodine when the solution is dropped in.]]> 2018-05-09 01:39:53 UTC https://padlet.com/lba6/f62v6np3g5jz/wish/259130107 couto139171 https://padlet.com/lba6/f62v6np3g5jz/wish/259130116 Ph 3 
Ph in mouth is different - different type of amylase
Use more syringes]]> 2018-05-09 01:39:58 UTC https://padlet.com/lba6/f62v6np3g5jz/wish/259130116 praka165021 https://padlet.com/lba6/f62v6np3g5jz/wish/259130147 2018-05-09 01:40:08 UTC https://padlet.com/lba6/f62v6np3g5jz/wish/259130147 loren136111 https://padlet.com/lba6/f62v6np3g5jz/wish/259130178 Our optimum pH was at 3. Because it was the shortest amount of time it took to break down all the starch into its monosaccharides. This is because we would think that our body’s average pH is 7, this is most probably because it is produced in the mouth, in our mouth there is nothing very acidic so it should be neutral, but because it goes into our stomach through our oesophagus. It has to be alkaline so it can’t hurt us and creates the neutralisation reaction. If we want to improve this experiment, we should first increase the possible amount of time we can measure. With only one spotting tile,  we can only measure 4 minutes at maximum, some of these reactions took longer than 4 minutes to complete.]]> 2018-05-09 01:40:21 UTC https://padlet.com/lba6/f62v6np3g5jz/wish/259130178 kagey581992 https://padlet.com/lba6/f62v6np3g5jz/wish/259130266 2018-05-09 01:40:52 UTC https://padlet.com/lba6/f62v6np3g5jz/wish/259130266 https://padlet.com/lba6/f62v6np3g5jz/wish/259130303 1. What was the optimum pH for amylase and why?

2. Why might the optimum pH in this experiment seem strange and can you think of an explanation?
3. One possible error and improvement for the method?

2. Was strange as amylase is in the mouth which would suggest the optimum may be around 7.
3.

I think it is strange the humans amylase optimum PH is 7 but I believe this is from a different animal there for has a different Ph in the mouth.
We may of  mixed up the syrintes at some point

2) The optimum pH for the amylase in your mouth is pH7, but the reason the pH for the amylase we used is different is because it is a different amylase, therefore it has a different pH.
3) We could use a colorimeter to more accurately determine the rate of reaction.]]> 2018-05-09 04:30:36 UTC https://padlet.com/lba6/f62v6np3g5jz/wish/259155507 teo825501 https://padlet.com/lba6/f62v6np3g5jz/wish/259155768 1) The optimum pH for amylase in this experiment is 3. It takes the shortest time to break down starch (turn the iodine to brown). 
2) The optimum pH (3) seems strange because usually the amylase in the mouth (used to break down foods) is 7. The amylase in our mouth is neutral (7) and Ph3 is very acidic.

Because it turned brown basically instantly. It was acidic to help break down the starch.
2: It is strange because we thought we thought that 7, the neutral ph, would be most effective. And our saliva has a pH of 7.

It took the least amount of time to break down the starch and turn brown.
It was strange because we thought since it was in the mouth it would be pH 7.
To improve we could use a colorimeter so that we can improve the accuracy of the data.]]> 2018-05-09 04:34:51 UTC https://padlet.com/lba6/f62v6np3g5jz/wish/259155896 https://padlet.com/lba6/f62v6np3g5jz/wish/259155932 optimum pH: 3

2) Possibly because the amalyse is found in the mouth and the ph is 7

3) more spots in the plate so we can measure more time and more accurately as time increments are quite large

2. It is strange because you'd think the pH should be neutral, as saliva is supposed be neutral, so you'd think it would be 7 pH.
3. Making sure you use a stopwatch that sounds every 20 seconds maybe, as we would be delayed a few seconds sometimes because we didn't realize. ]]> 2018-05-09 04:39:28 UTC https://padlet.com/lba6/f62v6np3g5jz/wish/259156396 shin95301 https://padlet.com/lba6/f62v6np3g5jz/wish/259156469 1) 3

2. This is quite surprising as the pH of the mouth where amylase breaks down starch is around 7. Why is this?
3. One error would be making sure to extract the amylase solution from the test tube on time. Also, making sure that all iodine drops were of equal amount. And improvement might be to test more pH levels between the one we did in order to get an image of the bigger picture. ]]> 2018-05-13 09:13:30 UTC https://padlet.com/lba6/f62v6np3g5jz/wish/260203621
