HB105: Introductory Physiology The Action of Enzymes Introduction An enzyme is located in all living cells‚ and is a complex protein molecules. These protein based molecule act as a catalyst. This is a compound that aids chemical reactions without its own structure and state being changed during the process. Catalysts speed up chemical reactions‚ changing substrates into specific produce. Without these enzymes life would not exist. Enzymes are fundamental to all living things as they speed up

Anatomy and Physiology P5/M2 - Homeostasis Homeostasis is the need for an organism or a cell to regulate its internal environment (conditions within the fluid surrounding its body cells) by a system of feedback controls to stabilise health and functioning despite the outside changing conditions. This is important as this is what maintains and helps internal conditions (body temperature) to remain stable and constant. In humans homeostasis happens when the body regulates its body temperature in

Can Sensory Toys Help Autism In Children? While toys are essential in helping to develop a child’s motor‚ social and creative skills‚ are they helpful for children who suffer from autism or other special needs? The answer to that is most definitely‚ yes! In fact‚ stimulation from toys for these children is probably even more important and should be engaged with and encouraged as much as possible. Sensory toys help autistic children to problem solve‚ which is something many struggle with on a daily

certain task. In this lab we examined motor unit recruitment and muscle fatigue by electromyography (EMG) with dynamometry (DYN). When the motor unit in the muscle is activated signals are then generated‚ which result in muscle contraction. The impulse generated are a bit weak‚ yet can still be detected by the electrodes‚ EMG and is coupled by a measurements of power‚ DYN. When all the motor units reach its maximum strength the muscles will fatigue. Finally‚ the objectives of this lab were to determine

Physiology‚ Berry HOMEOSTASIS LAB ACTIVITY Introduction: Homeostasis means maintaining a relatively constant state of the body’s internal environment. The term used to describe a pattern of response to restore the body to normal stable level is termed negative feedback. When a stimulus (environment change) is met by a response that reverses (negates) the trend of the stimulus‚ it is negative feedback. As a result the internal environment is returned to normal. Pulse rate is constantly checked

Abstract: The Enzyme Lab results where when the liver was frozen‚ its reaction was fast‚ and when it was hot‚ it was slow‚ and the liver that was at room temperature reacted slowly to medium. Introduction: The Enzyme Lab is to conduct investigations to determine the most favorable conditions for the most efficient enzyme activity. Variables to be used testing include temperature‚ pH values and surface area. Enzymes are proteins that speed up the rate of chemical reactions‚ which would otherwise

REVIEW SHEET EXERCISE 6 Cardiovascular Physiology NAME: LAB TIME/DATE: 1. Define each of the following terms: • autorhymicity- The heart is autorhythmic. This means it generates its own rhythmic action potential independent of the nervous system. • sinoatrial node- is the impulse-generating (pacemaker) tissue located in the right atrium of the heart‚ and thus the generator of normal sinus rhythm. • pacemaker cells- are specialized cells that cause involuntary muscles and tissues to
