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

be able to carry on exercising. During acute exercise your muscle pliability increases which allows a greater range of movement which helps reduce injury. Acute Exercise will cause muscle fibre tears. This is generally known as micro- trauma. The myosin heads and the actin filaments will be pulled from the myofibrils. This damage will cause a release of chemicals that cause the soreness after your period of exercise. The chemicals released also stimulate repair and growth in the area to rebuild the

TOPIC 6‚ 11‚ & OPTION H: HUMAN HEALTH AND PHYSIOLOGY Digestive System Includes all the structures that are concerned with bringing food into the body to provide for the needs of the body’s cells. Each cell in an organism relies on a continuous expenditure of energy. Fats‚ carbs‚ and proteins are broken down during cellular metabolism and the energy derived from them is used to make ATP. The digestive system deals with: Ingestion‚ which is the bringing of nutrients into the body. Mechanical

Abstract The scope of this paper focuses on Salbutamol as a drug and the mechanisms behind; 1) The drug function. 2) Development of drug resistance. 3) The clinical features of drug resistant individuals. 4) How to diagnose them. 5) Management of these patients. Salbutamol resistance Salbutamol is a beta 2 adrenergic receptor agonist that is short acting and used in the management of conditions that cause bronchospasms/bronchoconstriction. These conditions mainly include

Chapter 1 Answers QUICK-CHECK questions 1 What are the special characteristics of the light produced by a synchrotron? In a synchrotron‚ electrons are accelerated to very high speeds (almost the speed of light). Light is created when the direction of movement of these electrons is changed (deflected) using magnetic fields. A characteristic of this light is that it is extremely bright. 2 a Explain why ice is less dense than water. Ice is less dense than liquid water because‚ as water solidifies

The Different Roles of Macromolecules in Biology.There are four types of macromolecules that I am going to describe: Proteins‚ carbohydrates‚ lipids and nucleic acid. I will also describe the functions and why they are important in our bodies. Proteins Proteins are polymers of amino acids that are joined head-to-tail in a long chain that is then folded into a three-dimensional structure unique to each type of protein. The covalent linkage between two adjacent amino acids in a protein (or polypeptide)

BIOL 2010 ANATOMY AND PHYSIOLOGY I Chapter 4: TISSUES AND MEMBRANES Outline of Notes I. Introduction. A. General: Cells are highly specialized and interdependent on one another. Groups of similar cells performing similar functions are called Tissues The study of tissues is called Histology. Organs are made of tissues. A detailed understanding of tissues will greatly help your understanding of organs and organ systems later in this course. Tissues are classified into 4 main types:
