Cells are the structural and functional units of all living organisms; each specialised to perform dedicated duties throughout their life span. All living organisms can be sorted into one of two groups depending on the fundamental structure of their cells. These two groups are the prokaryotes and the eukaryotes. A Prokaryote cell is the first form of cells for many millions of years until the eukaryote cell evolved from the prokaryote cell‚ which created life. Prokaryote cells are organisms made

ENZYME STRUCTURE AND FUNCTIONS: Enzymes are biological catalysts. They increase the rate of reactions by a factor of between 106 to 1012 times‚ allowing the chemical reactions that make life possible to take place at normal temperatures Definition of enzyme: A protein with catalytic properties due to its power of specific activation is defined as an enzyme. STRUCTURE Enzymes are proteins their function depends on its complexity. The reaction takes place in a small part of the enzyme

New legislation would require enrollment applications for the New York State Health Insurance exchange to ask enrollees if they would like to register as organ donor. This question already shows up when your applying for a drivers license or renewing your license. “The more ways we can ask New Yorkers to register‚ the better. This legislation is creating more opportunities for people to sign up to save a life. Organ and tissue donation

Functions of the cells The functions of cells are shown in the body which is comprised entirely of cells. Every cell also has its own or more than one job to do. The cell membrane The cell membrane also known as the - plasma membrane. It consist of two layers of a fatty type substance. Its function is to protect the inside and the outside of the cell by allowing certain substances into the cell‚ while keeping other substances out. It also serves as a base of attachment for the cytoskeleton in some

Chapter 3 Cell Structure and Function Section 3.1: Cell Theory: Cells are the smallest building unit of living organisms that can carry out all processes required for life. Almost all cells are too small to see without the aid of a Microscope. Although glass lenses used to magnify images for hundreds of years‚ they were not enough to reveal individual cells. The invention of Compound microscope was in the late 1500s by the Dutch eyeglass maker Zacharias Janssen. In 1665‚ the English scientist

Hammer Head Shark Organ Structure and Functions The hammer head shark contains multiple organs that are suited for their environment in the Great Barrier Reef. Their skin‚ which is an integument organ‚ is made of an atmosphere of dermal denticles or placoid cells. These denticles and cells are tiny‚ hard‚ tooth like structure that makes the skin tough like sandpaper for protection. Their inner organs are much like that of a human. They contain the stomach‚ spleen‚ pancreas‚ rectum and the

11. Identify the four basic types of tissues and the functions of each tissue type. There are four different types of tissue. They are; nerve‚ epithelial‚ connective‚ and muscle. The nerve tissue is made up of neurons that receive and transmit electrical impulses‚ this is their function. There are several different types of epithelial tissue. First there is simple squamous epithelium tissue. This is a single layer of cells that is in the lining of blood vessels‚ the lining of the pulmonary alveoli
