Overview

Cells have to carry out numerous functions to survive. These function range from replication and energy conversion to molecule transport and the various signaling used in cellular communication. While they seem to be relatively fundamental processes, many of them require complicated cascades of biochemical reactions. In this section, you will learn about some of the important cellular processes that are essential to the survival of cells. Choose an option from below to proceed.

	Molecule Transport Cells must transport nutrients and other molecules in and out of their cytoplasm. Find out the machineries involved in this process.
	DNA Replication The most important goal of a cell is to survive. Come here to find out how the cell copies its genetic information.
	Reproduction Cell replication can either occur via mitosis or meiosis. Click here to find out the difference and the purpose of each.
	Protein Synthesis Proteins have diverse functions inside the cells but how are proteins made? Come here to find out more.
	Cellular Metabolism Animals consume food to get energy. However, the bread and hamburgers we eat must be converted into more useful forms of energy.
	Cellular Signaling Cells need to communicate with each other to synchronize their functions. Find out how this is done.
