One external factor that could affect a child’s development is poverty and deprivation. This splits into 5 categories; diet‚ housing‚ education‚ play & leisure opportunities and aspirations & expectations. If a child is born into a family of low-income‚ the 5 categories above tend to be negatively affected due to a lack of money and opportunities. A poor diet‚ for example‚ can mean that children are fed an unhealthy diet of processed food‚ meaning they are not as healthy and they are unlikely to

place at an incredibly fast rate; however‚ without enzymes‚ these reactions could possibly take several years to complete. An enzyme is a macromolecule‚ generally a protein‚ that lowers the activation energy of a reaction without being changed by the reaction‚ and this causes the reaction to occur much faster than usual (Campbell et al.‚ 2014). The act of speeding of a chemical reaction is called catalysis‚ and molecules that perform this are called catalyst. Enzymes act as catalysts‚ and there a

Wan Ching Man 5C(21) Effects of temperature on the activity of lipase Aim: To investigate the effects of temperature on the activity of lipase enzyme on milk which contain fats or lipids. Introduction: Enzyme is a kind of biological catalyst that made up of protein. It can speed up the metabolic reactions on various kinds of substances. Like lipase can break down lipid into glycerol or fatty acids in milk. Since enzyme is made up of protein which easily affected by varies temperature. This

Australia’s economic restructuring‚ particularly in regional and coastal areas. There are many aspects such as history‚ attitudes and culture to contemplate when defining the meaning of leisure‚ though it is essential the participation of recreational activities free from any other obligations or responsibilities (Lynch & Veal 2006‚ p. 25).

Enzyme are a very important component in living organisms. If enzymes did not exist than life itself would not exist (Lab Manual 3 pg. 1). They help in many different ways that are useful to the body of living organisms. Enzyme are used to speed up chemical reactions (Lab Manual 3 pg. 1). Through this process‚ they are considered very unique because they are not altered or consumed within the reaction (Lab Manual 3 pg. 1). This is why enzymes are considered biological catalysts. They also do not

Factors Affecting The rate of Enzyme Activity Prediction: As the temperature increases the rate of enzyme activity will also increase‚ thus increasing the rate of reaction. However‚ if the temperature is too high the enzyme will denature.

Enzymes are biologic polymers that catalyze the chemical reactions that make life as we know it possible. The presence and maintenance of a complete and balanced set of enzymes is essential for the breakdown of nutrients to supply energy and chemical building blocks; the assembly of those building blocks into proteins‚ DNA‚ membranes‚ cells‚ and tissues; and the harnessing of energy to power cell motility‚ neural function‚ and muscle contraction. With the exception of catalytic RNA molecules‚ or

Enzymes are responsible for multiple reactions that take place naturally in the living organisms. The purpose of the enzymes lab was to investigate how the enzymes play a role in a reaction‚ affecting the rate of reaction (ROR). Interestingly‚ we tested how the enzymes affect the reaction rate at multiple temperatures (0‚ 23‚ 37‚ 50‚ 70‚ and 95 C). It was predicted that an increase in temperature will elevate the thermal activity of substrate which increases the chances the substrate molecules will

The aspects of using tobacco are influenced and determined by individual factors such as self-image and perceptions‚ social factors such as the societal norms‚ environmental factors such as economics and advertising‚ the traditional use of tobacco as a cultural factor‚ acculturation alongside the historical context of the tobacco industry in different communities. Both the patterns and behaviors on the use of tobacco have led to the difficulties in both its measurement and study. Nevertheless‚ the
