Enzymes are catalysts that increase the rate of chemical reactions organisms‚ allowing cells to break or build things instantly. The structure of an enzyme is essential to its function. Enzymes are proteins‚ made up of 100-1000 amino acids bonded together in chains. These chains are folded/coiled into a unique 3-D structure that allows them to bind to a reactant‚ called a substrate at an active site. Enzymes are flexible‚ and therefore can change it’s shape to better accommodate its substrate; this

athletes’ performance. The purpose of this paper is to discuss the beneficial effects that music can have on athletic performance and to provide examples from research. Music can benefit performance because it controls arousal rates‚ elevates moods‚ reduces exertion rates‚ creates dissociation from pain and fatigue‚ creates synchronization‚ enhances ability to learn motor skills and creates flow states. Synchronous music is beneficial

The rate was still calculated for each experimental tube. It is important to calculate the rate because if one experimental value stays at a relatively high constant rate yet another changes from a low value to a high value then that won’t be shown unless the rate of each is taken. The rate is able to show the change in values rather than just the individual values of the data. It is calculated by

All children are unique and develop at their own rate but they tend to follow a similar pattern. There are a number of areas of development like‚ Physical‚ communication‚ Social‚ emotional‚ behavioural‚ Intellectual and moral development.

show that music possesses properties that affect the growth rate of plants in different ways. These properties may be the wavelength of the music‚ its frequency or even its tempo. According to a study conducted by Margaret E. Collins and John E. K. Foreman‚ entitled The Effect of Sound on the growth rate of plants (2001)‚ plants growth is directly affected by sounds of varying frequencies. They observed that when plants are exposed to pure tones‚ it affects the growth of the plant. This was due to

Do you know what Potassium cyanide is‚ what it does to your body‚ and what its use is? This paper will answer all those questions‚ and will specifically examine how potassium cyanide affects the body and how it is used. Potassium cyanide is a white crystalline salt solid that has a faint‚ bitter-almond like smell. It’s empirical formula is KCN. The taste of KCN is described as burning the tongue and tasting acrid. This compound deliquescent‚which means that it tends to dissolve. The appearance is

of the plasma membrane found within and around all cells’ The plasma membrane surrounds all eukaryotic and prokaryotic cells. Eukaryotic cells have membrane bounded organelles whereas prokaryotic cells do not. The plasma membrane forms the boundary between the cell cytoplasm and the environment. Its function are to allow different environments to be established inside and outside the cell. It also controls the movement of substances into and out of the cell. The cell surface membrane which surrounds

Jared Choy Mr. Dahlhausen Period 6 17 November 2014 Does Age affect Reaction Time? When a person sees a health care provider and the doctor hits the person’s knee with a rubber mallet‚ the person’s leg kicks up on its own. This happens because when the doctor hits your kneecap‚ the tendon under it gets stretched‚ which in turn will send a signal to an awaiting motor neuron so it can command the muscle to contract. Let’s take for example the reflex arc. A reflex is the involuntary movement of the
