Effects of pH on fungal amylase activity BI 211 November 25‚ 2011 Introduction In recent years‚ the uses of microorganisms have become a huge importance to industry and sparked a large interest into the exploration of enzyme activity in microorganisms. Amylase is one of the most widely used enzyme required for the preparation of fermented foods. Apart from food and starch industries‚ in which demand for them is increasing continuously‚ amylase is also used in

The Effect of Pressure on Students to Get Good Grades Has there ever been a time where you have been pressured to get good grades in school? When this situation has occurred was it stressful and nerve-racking at the same time where you felt you could not do it anymore? In this paper I will explain the causes of pressure on students to get good grades and the effects of them. With pressure being the constant state of worry and urgency‚ has caused stress and difficult to students to excel and

Increased muscular activity results in a decreased partial pressure of oxygen‚ an increased partial pressure of carbon dioxide‚ a reduced PH‚ and an increased temperature. Consequently as much as 73% of the oxygen picked up by haemoglobin in the lungs is released in skeletal muscles during periods of physical exercise. Utilisation When we inhale air‚ oxygen is transported to the lungs and can be utilised by the body to stay alive. Oxygen is used to produce ATP for energy “the principle energy

Effects of Human Activities on the Lake Ecosystem I. Introduction On the first exercise of the Environmental Biology class‚ the students have learned what an ecosystem is and what its significance to the survival of the living and non-living are through analysis of forest and agro-ecosystems. The ecosystem as the basic unit for ecological study (Evans‚ 1956) consists of the complex of interacting organisms inhabiting a region with all the non-living physical factors that make up their environment

one: Activity-based costing (ABC) is an accounting system that aids in providing various methods of calculating dynamically and practically the true cost of doing business for manufacturers and services. The core characteristic of ABC is that overhead costs are driven by activities themselves not products. ABC assigns a company’s overhead costs‚ which are the indirect cost such as electricity‚ lighting‚ heat or marketing‚ into the product’s cost. Specifically‚ ABC applies nonunit-level activity drivers

These problems effects people’s lives negatively and people are affected by each other easily. This is like a loop and each person is affected by another person.

Investigate the effect of temperature on amylase activity Introduction Amylase is an enzyme that catalyses the breakdown of starch into sugars. Amylases are found in almost all plants‚ animals and microorganisms. Large amounts of amylase occur in germinating cereals‚ and in the pancreas and saliva of higher animals. Aim The aim of this experiment is to find out the rate of reaction between amylase and starch in a range of different reaction temperatures. Hypothesis As the reaction
