Students experiment using the basic principles of gel filtration. They use the gel filtration technique for testing for the presence of specific substances. Students discover that starch is a larger molecule than glucose.

Which food molecules must be present for cellular respiration to occur? Scholars view an informative presentation to better understand the process of cellular respiration. It details each step, focusing on the locations and the four main...

Students examine the characteristics of lactose and lactase.  In this enzyme lesson students study the lactose in milk and its rate of dissolution.

Students examine what amylase is and its history.  In this digestive instructional activity students study the effect amylase has on starch and how temperature affects the rate of activity.

For this biochemistry worksheet, students review amino acids, proteins, lipids, and carbohydrates. This worksheet has 29 multiple choice, 8 fill in the blank, and 3 short answer questions.

In this chemistry of life worksheet, students will review key terms of plant cell structure and chemistry by reading 13 clues to complete the puzzle. Word bank is included.

Biology classes will bubble with excitement as they complete this assignment. Beginning with an informative overview of cellular respiration and fermentation processes, the highlight comes as an experiment in determining the rate of...

This is not they typical set of teacher instructions. It is an organized chart of the important organic compounds. For each, the involved elements, the name of the building block monomers, the names of polymers, extra information, and a...

In this biology worksheet, students review the procedures used to complete the lab activity and then examine the purpose and add the information while answering the questions.

Students are taught how enzymes enable chemical reactions to occur a body temperature and how the lack of enzymes in the body can cause problems in the break-down and absorpion of nutrients. They match up different enzymes with the...

Diagrams with annotations are shown on each of these eighteen slides, which summarize the processes of respiration. The focus is on the 3-step oxidation process and the Krebs cycle.  Students should be able to follow these slides...

This series opens with diagrams of experimental setups. A data table is displayed and questions are asked, indicating that the intent is for lab groups to perform the depicted experiments. At slide twelve, a coherent lesson about the...

Ten reactions involved with the process of glycolysis within cellular respiration are summarized here. The aerobic stages and anaerobic interactions leading to fermentation are detailed and wonderful diagrams to support the information...

Students are often confused by the huge amount of information and detail that can be learned about respiration.  This is a great presentation summarizing the main 4 stages of cellular respiration. It is clear and uses diagrams and...

If you need a clarification of the electron transport chain for your pupils, then this slide show will be a great help. There are nice images of the membranes and elaborations of chemiosmosis which will provide learners support with...

The main concepts behind how ATP transfers energy are explained in this Ap Biology PowerPoint. The diagrams convey the information that students need for any test regarding phosphorylation. The steps are clear, and should help...

Information about digestion of various food components is given in this PowerPoint. The diets of herbivores and carnivores are compared, and there are many diagrams giving details of their digestive system specializations. The...

From the light reaction to the Calvin cycle, this presentation contains information about the various stages of photosynthesis.  This is a great supplement to some of the biochemistry-heavy presentations about the specific...

As your class views each slide, they will be introduced to the organelles and structure of the cell.  Details about structure and function are given and also some trivia about their frequency and population. There is also some...

A complete overview of oxidation, reduction, and how electrons are moved in respiration. You could use this slide show to elaborate on the concept of harvesting stored energy, and to summarize the stages of aerobic and anaerobic metabolism.

Starting with a diagram of the kidneys and urinary tract of the human, this sheet has questions about excretion, blood concentrations of hormones, gland feedback mechanisms and the effects of some hormones.

Students make a starch-glucose solution and pour it through gel in order to separate the starch from the glucose. They examine how starch is a larger molecule than glucose and test for the presence of these substances using other...

Colorful pictures and graphics make this a visually-appealing presentation on animal nutrition. Be aware that two of the sixteen slides include blank graphic organizers, so you will need to find the other existing version of this...

Leaf structure and its specializations for photo-respiration are detailed here.  Slides provide information about Photo-respiration biochemistry and its impact.  A class learning about classic respiration will appreciate the...
