Enzymes are found in all living organisms. They are present to speed up or accelerate a chemical reaction; referred to as a catalyst in a chemical reaction. They are essential to obtain rates to sustain life as without enzymes rates would be too slow to provide for life. Molecules at the start of the process are called substrates, the enzyme will then convert these into changed molecules which are called products, after this process the enzymes maintains the same shape. (Berg et al. 2002).…
Rate of Reaction for Enzyme Peroxidase
When analyzing living organisms, it is merely impossible to overlook the role that metabolism plays. Metabolism, is a series of chemical reactions that occur in a living organisms cells. When referring to metabolism, one must also note that metabolism contains two distinct metabolic pathways, catabolic and anabolic. Catabolic pathways involve the process of breaking down molecules in order to obtain the energy needed by living organisms. Meanwhile,…
50% of the vitamins.
Vitamin D that is synthesized in the skin from cholesterol would enter the capillary system and be transported by DBP into the peripheral tissues. Only very little excess vitamin D would be stored in the liver for later use.
Metabolism of vitamin D is activated by two hydroxylations. The first would occur in the liver while the second is carried out by the enzyme a-1-hydroxylase in the kidney. The first hydroxylation would produce 25-hydrocy-vitamin D3 while the second…
to lose weight. Choose a weight-loss program (0.25 marks) and evaluate whether the plan offers a nutritionally sound way to lose weight using the principles of energy metabolism and energy balance (1.25 marks)(Note, you will need to explain the weight-loss program, the details of the diet promoted, how it may “manipulate” metabolism to shift energy balance, and what body region (e.g. fat, muscle, water) is influenced by the diet resulting in weight-loss).

converting carbs into fat. This greatly impedes the accumulation of fat in the body; thus enhancing weight loss.
3. Improves the Metabolism
Garcinia Cambogia is very effective in creating an efficient metabolic environment because HCA can balance the chemical reactions taking place in the body. When high levels of HCA are present in the body, the forces of metabolism tend to expend much more energy by tapping into the fat reserve. The resulting imbalance in the energy levels, effectively leads…
It is also called anabolism or biogenesis. It is a enzyme-catalyzed method in which substrates are transformed into complex products. In this process simple compounds change or convert into other compounds or they join together to form macromolecules.
In this process gluneogenesis is responsible for the production of glucose from non carbohydrate originator.
Actually biosynthesis is an enzyme-catalyzed process in which substrates are converted into complex compounds.
For example, OSBP1 protein regulates transport of sphingomyelin and ceramide molecules (Perry and Ridgway, 2006). Moreover, it can also influence sterol metabolism via negative regulation of ABCA1 transporter through regulation of its gene expression and protein destabilization (Bowden and Ridgway, 2008). The regulation of ABCA1 is also mediated by ORP8 (Yan et al., 2008). Overexpression or knock-out experiments…
athlete's energy intake is timing. It is important to ingest carbohydrates before résistance training in order to optimize work capacity during the workout and to co-ingest carbohydrates and proteins after a training session to promote muscle protein metabolism as well as accelerate the restoration of glycogen…
cocaine when it is sniffed. This can be considered as one example of this type. Smokeless tobacco could be another example.
There are 2 major spheres that need to be taken into consideration while designing a drug:
1. Drug target 2.Drug metabolism
There are four stages in the physiological handling of a drug:
Absorption: Drug absorption is the process by which drugs move into the blood stream after administration. Absorption affects the bioavailability of…
