Carolina BioKits®: Exploring with Pectinase: An Introduction to Enzymes (with voucher)

$60.00
(in stock)

Description

For 32 students working cooperatively in 8 groups of 4. Introduce your students to enzymes and how temperature and concentration affect an enzyme's ability to convert reactants into products. In this activity, students add increasing amounts of the enzyme pectinase to applesauce and observe how much juice is released at various temperatures. They then mathematically depict the effect of increasing enzyme concentration by graphing the volume of enzyme used versus the volume of juice released. Note: This kit includes a voucher to request perishables later at your convenience. Contact us or return the voucher to request delivery of perishable materials.
