Biofuels

What is the purpose of an enzyme

To speed up a reaction

A spectrometer measures the ___ of light as it passes through the sample

Absorbance

what is the part of an enzyme where the substrates binds

Active Site

Enzymes are necessary in biofuel production because they help break down ___ into sugars used to make fuel

biomass

The ___ variable in the biofuel lab was the amount of absorbance

dependant

one advantage of biofuels is

It is renewable - no carbon emmissions

one disadvantage of biofuels is

it takes up space

is the stop solution was not added to the biofuel lab, the reaction would have ___

keep going

what is the order of Micropipetting steps

1. press the micropipette plunger to the first stop

2. Dip the pipette into the liquid

3. Slowly release the micropipette plunger to collect the liquid into the tip

4. Remove the pipette tip from the liquid, then release the plunger

5. Place the tip where you want to put the liquid

6. Press the micropipette plunger to the second stop

what was the purpose of the stop solution

To stop the reaction from continuing

What was the purpose of using a blank for the spectrometer?

To set a baseline so the machine only measures the sample

What is the purpose of using a standard curve

To identify the amount of product

Steps on how to read a standard curve

1. Find the absorbance of your cuvette on the y-axis

2. Draw a line across to the standard curve, then down to the x-axis

3. This will tell you how much product was in your sample
