General Biology I - This course is a study of the fundamental principles of biology concerning the structure and function of cells, heredity, and biotechnology. Recommended for LAS students, especially those who will be pursuing science-related careers. No dissection is required.
Enzymes in Living Organisms (04:47)
From Title: The Role of Enzymes
Human bodies contain two types of enzymes: intracellular and extracellular. Plants, fungi, and bacteria often contain enzymes not produced in humans. Enzymes are named by their substrate with the suffix 'ase'.

This video takes a close-up look at the lowest common denominator of all life: the cell. It illustrates essential cellular processes—transportation of materials, communication, energy transfer, protein-building, waste disposal, movement, and the all-important mitosis and meiosis—as well as key cellular landmarks like the nucleus, ribosomes, mitochondria, the Golgi complex, the endoplasmic reticulum, and lysosomes. Special attention is given to recent advances in biotechnology.
Plants, like animals, reproduce, evolve, and adapt. Plant cells contain structures not found in animal cells, including cell walls and chloroplasts that contain chlorophyll used during photosynthesis.
Introduction to Enzymes (03:04)
From Title: The Role of Enzymes
Most enzymes are proteins produced inside cells through protein synthesis. Enzymes combine with substrates to facilitate the formation of products. Enzymes are specific and do not change the equilibrium position or a reaction.
