Maintaining a Balance 1. Most organism are active in a limited temperature range The role of Enzymes in metabolism‚ their chemical composition and specificity on substrates Role of enzymes * Enzymes are organic catalysts. They are protein molecules that increase the rate of the reactions in living organisms. * Without enzymes‚ metabolic reactions at body temperatures would be too slow to produce sufficient energy to maintain life * Intracellular enzymes are used in the cells

which are needed to live. Some of those elements are calcium‚ phosphorus‚ potassium‚ sulfur‚ sodium‚ magnesium‚ and many more. In the circulatory system‚ two elements that are critical to the circulatory system are iron and oxygen‚ without these two elements it would be impossible for the system to function. The circulatory system is an organ system that permits blood and lymph circulation to transport nutrients (such as amino acids and electrolytes)‚ oxygen‚ carbon dioxide‚ hormones‚ blood cells

From Tissues to organs Cells combine to form tissues and tissues combine to form organs. Cells combine to form four primary tissues: - Epithelial tissue - Connective tissue - Muscle tissue - Nerve tissue BACKGROUND:A tissue is a group of cells that have a similar

people) Normally‚ neurons in the central nervous system (the brain and spinal cord) cannot regenerate injured nerve fibers‚ limiting people’s ability to recover from brain or spinal cord injuries. Repair of the central nervous system and restoration of voluntary motor activity through axonal re-growth has long been considered impossible in mammals. Over the last decade‚ numerous attempts proved disappointing overall. While repair of the central nervous system has long been considered impossible have

They are many different areas in the field if neuroscience. Neuroscience deals with the five senses‚ anything connected to the nervous system‚ the brain‚ anything that sends information to and from the brain‚ etc. Many of these things go from simple ideas and concepts to the complex coding

simultaneously and very quickly. The brain itself requires extremely fast speeds to operate at even at the simplest level. How do the biological tissues of our body support such rapid coordination of the brain‚ limbs‚ and sensory input? They do so with nervous system tissue that imitates electrical wiring. A series of photomicrographs and schematic illustrations show myelinated nerve fibers. Panel A is an illustration of a single neuron with major structures labeled. Panel B is an illustration of a cross

The nervous system is affected because the motor neurons will stop working which makes it harder for the muscular system to do its job. The nerve cell make an important chemical called dopamine which sends signal to the brain for movement without the nervous system the body will be hard to move because if the dopamine can’t end the signal the body can’t move which can be very difficult. The muscular system permits movement and circulate blood if the muscular system stop working it can

HUMAN AS A COMPLEX ORGANISM The human body is a complex system of cells‚ most of which are grouped into organ systems that have specialized functions. These systems can best be understood in terms of the essential functions they serve: deriving energy from food‚ protection against injury‚ internal coordination‚ and reproduction. The continual need for energy engages the senses and skeletal muscles in obtaining food‚ the digestive system in breaking food down into usable compounds and in disposing
