molecule. Each of these phosphorus atoms is at the center of an atomic group called a phosphate. The phosphate groups are linked to one another by chemical bonds called phosphate bonds. The energy of ATP is locked in these bonds. The energy in ATP can be released as heat or can be used in the cell as a power source to drive various types of chemical and mechanical activities. For example‚ when the terminal phosphate group of the ATP molecule is removed by hydrolysis (a decomposition process that occurs

Name: Professor`s name: Course number: Date: Metabolic Pathways of Drugs The principal site for drug metabolism in the human body is the liver organ. The process of metabolism usually inactivates drugs though some drug metabolites are pharmacologically in active status. Inactive substance which has a metabolite that is active is referred to as a prodrug. Drugs are metabolized

Phosphates are present in many natural waters‚ such as lakes and streams. Phosphates are essential to aquatic plant growth‚ but too much phosphate can lead to the growth of algae and results in an algae bloom. Too much algae can cause a decrease in the amount in dissolved oxygen in the water. Oxygen in water is affected in many different ways by phosphates Phosphorus is usually present in natural waters as phosphate(Mcwelsh and Raintree‚ 1998). Phosphates are present in fertilizers and laundry

In this experiment‚ a reaction is considered where a colorless Paranitrophenol Phosphate (PNPP) is converted to the yellow paranitrophenol (PNP) through the action of an enzyme called alkaline phosphatase. This enzyme normally acts on molecules that have a phosphate group by cleaving it. The main purpose of the experiment is to study the kinetics of alkaline phosphatase when acting on a conversion of PNPP to PNP by measuring

“People with goals succeed because they know where they’re going.” –Earl Nightingale My Visionary self is usually the driving force of my ambitions for life‚ love‚ success‚ educational goals‚ and so on. I sometimes question whether this is a development of my own doing or has it been created by the interaction between others and myself. For instance my parents have been supportive and promising in all the decisions I make for myself. They have given me the ability to think for myself as well as

The mTOR Pathway Introduction The mammalian target of rapamycin (mTOR) signaling pathway integrates both intracellular and extracellular signals and serves as a central regulator of cell metabolism‚ growth‚ proliferation and survival. Discoveries that have been made over the last decade show that the mTOR pathway is activated during various cellular processes (e.g. tumor formation‚ insulin resistance‚ adipogenesis and T-lymphocyte activation) and is deregulated in human diseases such as cancer
