Cell Fractionation: Isolation of Mitochondria from Cauliflower and Determination of Specific Enzyme Kinetics Introduction Mitochondria is an organelle found in eukaryotic cells that play a role in biochemical processes such as respiration and energy production. Mitochondria even play an important role in apoptosis‚ or programmed cell death. This is achieved by disruption of electron transport‚ oxidative phosphorylation‚ and ATP production or even the release of proteins that trigger activation

genetic material and the study of how that material reacts during the life of the cell. Strictly speaking‚ mitosis is the division of the nucleus into two daughter nuclei that are identical to one another and to the parent nucleus. Mitosis is part of the cell cycle which also includes chromosome replication and division of the cytoplasm i.e. cytokinesis. The chromosomes are always present in the nucleus but they are most easily seen when the nucleus divides. During this division process chromosomes contract

Stem cells are unique because they have the ability to generate new cells of any kind during early life and growth. There are about 200 different types of cells in the body; such as muscle‚ skin and brain cells. Most of these cells have to be repaired or replaced once in a while. For example our taste buds are replaced every 10 days‚ skin cells every couple of weeks and liver cells every 300-500 days. Stem cells serve as an internal repair system dividing essentially without limit to replenish

Cell Reproduction Dr. Susan Kennedy Introduction to Biology January 28‚ 2012 Introduction Cellular reproduction is the process by which cells duplicate their contents and then divide to yield two cells with similar‚ if not duplicate contents. Life as we know it depends on the ability of cells to store‚ retrieve and translate the genetic instructions required to make and maintain a living organism. In this assignment‚ I will discuss two different types of cell reproduction

What are stem cells and what is gene therapy respectively? These are cells that have the potential to form many different types of cells found in the body. When stem cells divide‚ can form more stem cells or other cells that perform specialized functions. Embryonic stem cells have the potential to form a complete individual‚ while adult stem cells can only form certain types of specialized cells. Stem cells to continue to divide throughout the lifetime of a person. The use of recombinant DNA

general relationship between light intensity and photosynthesis that could normally be seen had the experiment taken place without errors. The graph should show an increase in arbitrary units the further away from the light source the beaker is because the greater the distance from the light source‚ the lower the light intensity and so less photosynthesis would take place in the algal balls. This would result in more CO2 being present because it wouldn’t be being used up during photosynthesis. The
