6. Enzyme reports-outline to write the report

The enzyme report is based on only 2 exercise, substrate specificity and  importance of cofactors. Click on the link and it will open the format, The statistic data for both the experiments is attached here



Homework: Homework (lab report) is to be printed out completed  and turned in the following week. Information for the homework is from doing the lab. Each homework will open up the day of the lab and close on sunday night. Students should have attended the lab and will have to complete each homework on their own .

BIOLOGY LAB QUIZZES: Check schedule to see quiz dates. Each quiz is worth 20 points. Each question is worth 1 point.

Biology lab quiz-1- review:


Practice quiz

1.The metric conversions and scientific notations.

Moving from larger unit to smaller unit, you move decimals to the right of the scale, smaller to larger move to the left of the scale.

eg. Kg to grams will be moving the decimal 3 spaces. 1.0 Kg will be 1000.0 grams.

The scientific notation will be 1x10 to the power of negative 3.

Moving decimal to the right the exponent will be negative , moving decimal to the left will be positive

1000 gram to Kg will be 1x10 to the power of positive 3

2. Know the metric prefix which can be kilo, hecta, deci,centi,milli,micro,nano

3. Metric label or unit for weight is grams, length is meter and volume is liter


LAB-2 spectrophotometer

1. Visible spectrum wavelength number for green which is 490-575 approx, blue is before green and yellow comes after green
