all of the work being done inside any cell is being done by enzymes. If you understand enzymes, you understand cells. A bacterium like E. coli has about 1,000 different types of enzymes floating around in the cytoplasm at any given time. Enzymes have extremely interesting properties that make them little chemical-reaction machines. The purpose of an enzyme in a cell is to allow the cell to carry out chemical reactions very quickly. These reactions allow the cell to build things or take things apart

isotopes of that element. Elements come together to give up, accept or equally share electrons to make molecules. The smallest part of an organism is a cell. Some single-celled organisms are free-living and contain structures, called organelles that allow them to be self-sufficient. More complex organisms are multicellular. In the case of a human, cells are organized into tissues. These have a common function like a muscle. Tissues are organized into organs like the heart. Organs are organized into organ

Introduction to Biology March 1, 2014 Gene therapy is the transplantation of normal genes into cells in place of missing or defective ones in order to correct genetic disorders (Genetics home reference, n.d). This is a promising treatment for diseases such as inherited disorders, some types of cancer, and certain viral infections. The way this treatment works is by introducing genetic material into cells to compensate for genes that are abnormal or are not making beneficial proteins. Mutated genes

Microbiology Unit 2 ass 1 Cellular Structures A cell needs many things to fully function. Three important parts of a cell is the cell wall, plasmid and the flagellum. The cell wall gives the cell a barrier from things around it. It protect the cell. Plasmid is a DNA molecule. Flagellum is a “tail” that wipes back and forth allowing the cell to move. Plasmid is found in bacteria. They need a host to live of. It is a clone of the bacteria’s DNA. It typically provided the bacteria with

Unit 5: Anatomy and Physiology for Health and Social Care. Name: Fatimah Al_Asadi Teacher name: Miss Bull Name: Fatimah Al_Asadi Teacher name: Miss Bull Aim and purpose This unit aims to enable learners to understand aspects of the anatomy and physiology of human body systems. Learners will be able to gain an overview of the organisation of the human body before looking at how body systems work together to provide energy for the body. Learners will have the opportunity to investigate

Functions of the component of the human cell.( http://www.slideshare.net/kristenaoconnor/cell-organelles) Cell membrane: the cell membrane also known as plasma membrane is the biological membrane that separates the interior cell from the outside environment. It provide support and protection for the cell. It serves as the entrance and exit of the cell. Cytoplasm: cytoplasm is a jelly like material that fill the cell. It contains food and water for the cell. It holds the organelle in place. It is
