Photosynthesis
Step through the light and dark stages and see what goes in and comes out at each point.
Respiration
Follow glucose through glycolysis, the Krebs cycle and the electron transport chain.
Enzyme Activity
Change temperature and pH and watch the rate of reaction and denaturation respond.
Osmosis and Diffusion
Move a cell between hypotonic, isotonic and hypertonic solutions and see what happens.
Mitosis Stage Sorter
Put the stages of mitosis into the right order and check your reasoning.
Mitosis vs Meiosis
Step through both divisions side by side, including crossing over and chromosome number.
ATP Builder
Assemble adenine, ribose and three phosphates to build the energy currency of the cell.
NADP+ / NADPH Builder
Load the hydrogen carrier and see how it shuttles electrons between stages.
DNA Replication Builder
Pair the correct complementary bases as the DNA strand unzips.
Protein Synthesis
Transcribe DNA into mRNA, then read the codon table to build the polypeptide.
Punnett Square Builder
Build a cross and predict genotype and phenotype ratios.
Sex-Linked Cross Generator
Model X-linked inheritance and compare male and female offspring outcomes.
Heart and Circulation Flow
Follow one drop of blood around the double circulatory system, chamber by chamber.
