Chapter 4 Tissue: The Living Fabric 4.1 What are tissues? * Groups of cells that are similar in structure and perform a common or related function * There are four basic types of tissues: 1) Epithelial (covering) 2) Connective (support) 3) Muscle (movement) 4) Nervous (communication and control) * The study of tissues is known as histology 4.2 Preparing Human Tissue for Microscopy Requirements * Specimen must be fixed (preserved) * Specimen must be

Patrick McCrystal Enzymes: Natural Catalysts Enzymes are catalytic proteins‚ meaning they speed up chemical reactions without beingused up or altered permanently in the process. Although various enzymes use different methods‚all accomplish catalysis by lowering the activation energy for the reaction‚ thus allowing it tooccur more easily. Enzymes have very specific shapes (conformations). Part of the conformationis the active site of the enzyme‚ where the actual catalysis occurs. The specific molecule

The Roles and Functions of Health Care Managers Regina Mitchell HCS 325 The Roles and Functions of Health Care Managers The role of a health care manager can vary based on what type of facility they work in. For example a heath care manager that works in a hospital setting may oversee one department of the hospital with the help of other department managers. On the other hand a manager that works in a Clinic or doctor’s office may oversee the entire facility. Another variable in a health

In eukaryotic cell in slide #3 has organelles including a nucleus containing DNA and mitochondria energy organelles .Compared to the prokaryotic cell which has the DNA in the cytoplasm smaller and simpler and doesn’t contain a nucleus or other organelles‚ it does have cell membrane.

need of an organ can easily be saved but the transplant does not take place because of a wait list. Patients who urgently need an organ transplant who meet the criteria should get the organ(s) first. The reasons behind this is‚ if a patient is on their death-bed and in need of an organ not getting this organ can lead to potential death. Another reason is the chance of survival that the patient has urgent or nonurgent the organ should be able to continue to live. Lastly if we base organ transplants

Introduction: Enzymes are biological catalysts that permit cells to carry out the many functions that are required in a living system. Every enzyme has a specific substrate and a specific function. Enzymes alter substrates one of three ways: by adding something to the substrate‚ removing something from the substrate‚ or by changing its conformation‚ otherwise known as its shape. The structure of an enzyme and its ability to function exists because it binds to an active site‚ thus increasing the
