Introduction: The purpose of this experiment is to measure the effects of changes in temperatures and pH on enzyme activity in skeletal muscle‚ particularly the activity of lactate dehydrogenase (LDH). LDH is a glycolytic enzyme which converts pyruvate to lactate in the following equation: LDH Pyruvate+ NADH ------------ Lactate + NAD The reaction above can move in both directions‚

Reactions Enzymes are proteins found in living things that speed up chemical reactions. They aid in nearly all metabolic processes‚ such as food digestion‚ molecule synthesis‚ and the storage/ release of energy. An enzyme speeds up the rate of the chemical reactions by lowering the reaction’s activation energy‚ which means that by definition‚ an enzyme functions as biological catalyst. The activation energy is the energy that is used to get a reaction started. The function of an enzyme is dependent

CHAPTER I THE PROBLEM AND ITS SETTING INTRODUCTION This research paper is all about the factors that affect the behavior of high school students in dealing with other people. The researcher chose this kind of problem to be aware of the distinctive behavior of her fellow schoolmates‚ classmates‚ batch mates‚ etc. The researcher conducted this study to know the effective implications for the behaviors.

What is Enzyme? Enzymes are protein that acts as speed up reactions and break down molecules in our body. However‚ different enzymes only work on certain types of molecules. Enzymes can accelerate the reactions by more than one million times.(3) In our human body‚ there are a total about forty thousand types of enzymes and each catalyzes different kind of molecule.(3) The molecules that enzymes help to accelerate is called substrates‚ and when enzyme is combined together with the substrate‚ it

the heart‚ it increases which makes the left ventricle expand and adapt to a different situation. Due to this‚ the heart can register a higher level of blood and eject it at a faster rate to all living cells and membranes. This increases the heart rate because the movement of blood is faster than the resting heart rate. When performing a strength training exercise‚ the muscles contract allowing blood vessels to pass in and out. This builds the pressure in the body as well as increases the amount of

attitudes. Academic performance is affected by different factors. We cannot deny the fact that these factors could really affect the student’s academic performance. Some students who are influences by peer groups or barkadas tends to cutting class which may results their low academic performance. The peer factors like smoking may cause disease that would become hindrance to their success and this differs from other insight about those factors and their purpose and existence.

concentration on rate of an enzyme reaction. Enzymes are biological catalysts that lower a reactions activation energy making possible many of the reactions needed for life to exist. Enzymes have a high specificity which have been explained by many theories such as Fischer’s lock and key. Currently the most widely accepted theory is the induced fit hypothesis proposed by Koshland in 1958. This hypothesis solves some of the problems with the Lock and key theory and helps to explain why enzymes only catalyze

are light-independent. The rate of the first series‚ called the light reaction‚ can be increased by increasing light intensity (within certain limits) but not by increasing temperature. In the second series‚ called the dark reaction‚ the rate can be increased by increasing temperature (within certain limits) but not by increasing light intensity Photosynthesis involves the production of oxygen‚ and the uptake of carbon dioxide. These can be used as a measure of the rate of photosynthesis. This experiment

There are approximately 40‚000 enzymes living in one human cell‚ each responsible for a chemical reaction. Enzymes are complex 3D protein molecules created by amino acids‚ forming a unique sequence that produces hydrogen bonds‚ eventually formulating an enzyme within plants and animals (Boyle & Senior‚ 2002). Working alongside other molecules‚ they uphold a stable reaction system. The function of an enzyme is to aid and increase chemical reactions and organise metabolism‚ while maintaining homeostasis
