About this unit

Your cells are bustling hubs of activity! Every second, substances are being transported across membranes, molecules are being built up and broken down, and enzymes are catalyzing chemical reactions. In this unit, learn about these activities and how they come together to help cells carry out cellular respiration and photosynthesis, two of the most important biological processes on Earth.
Biology is brought to you with support from the Amgen Foundation
