Abstract: Escherichia coli is a gram-negative bacterium that is found in the human digestive system. Staphylococcus epidermidis is a gram-positive coccus-shaped bacterium commonly found on the human skin. In this study, we looked at the metabolism and physiology of both organisms on differential and selective media. Bacteria were grown and observed on Tryptic Soy Agar (TSA), Phenylethyl Agar (PEA), Mannitol Salt Agar (MSA), and MacConkey’s Agar (MAC). E. coli was able to grow on TSA, MSA, and MAC, and was...

Define Homeostasis Homeostasis refers to the property of cells, tissues, and organizes that regulates its internal environment and tends to keep up the regulation of the steadiness and constancy required to function properly. The body must constantly keep track of its internal conditions to keep up homeostasis. From body temperature to blood pressure to levels of distinct nutrients, each physiological condition encompasses a specific set point. A set point refers to the physiological value around which the typical range fluctuates....

Metabolism is what sustains life, it is the sum of chemical processes happening inside your body to keep you well and functioning at your fullest. From breathing to digestion and even the nervous network which is helping you to coordinate with the outside environment is a part of your metabolism. It is an autonomic process (which means you get to control any part of it) and is controlled by our brain. In short metabolism is the basis for all forms...

Discussion In the present study, we investigated the effects of lifelong, moderate-intensity exercise on blood metabolites through an NMR-based metabolomics approach. By comparing a lifelong exercise group, two long-term exercise groups, and a group that did not exercise, we found that moderate-intensity exercise has a strong effect on the blood metabolome up until midlife. From midlife to elderhood, the effect of aging becomes stronger than that of exercise. This unexpected finding comes in agreement with a study conducted by Falegan...

Metabolism is defined as the summation of all chemical reactions that occur and are involved inside of any cell or organism. Metabolism has two potential categories: catabolism and anabolism. In catabolism, molecules are broken down producing energy. In anabolism, combinations of certain compounds that are needed by the cells are produced including: DNA, RNA, and protein synthesis. The definition of bioenergetics is the metabolic passageways a cell takes to acquire certain energies. Nutrition science studies the specific relationships with food...

Metabolism Introduction Metabolism is biochemical system that the body uses to convert food to energy in order to maintain life and can be fully simulated at genome scale. Metabolism is partly genetic and largely outside of one’s control and changing it is always a matter of an ongoing considerable debate. In biology, metabolism is the only system that can be simulated at genome scale and is the best indicator for the cell’s physiological state and the biggest biological network fully...

These days individuals have accepted that for each 1 pound of muscle you gain, your body consumes an extra 50 calories. On paper, this sounds great. But it is not true, sadly. When we speak about metabolism like it’s something, we can control by swallowing a pill, bringing down some green tea, or running quicker. Let’s be evident about one thing: miracle metabolism boosters are not there. Regardless of what you find in promotions or hear in your running circles,...

We all love to eat, in fact, it’s essential for us to eat.

Introduction Yersinia pestis, the causative agent of plague, has been historically accountable for greater than 200 million deaths throughout three pandemics. Zoonotic maintenance of plague occurs through the ability of it propagation and circulation amongst rodent reservoir hosts and flea vectors. Upon consumption of an infected mammalian blood meal by a naĂŻve flea, Y. pestis proliferates in the flea midgut. Y. pestis forms a biofilm in the flea proventriculus which prevents the passage of blood during subsequent feeding attempts. Moreover,...

It is often presented that people need to increase their iron intake by consuming more red meat or green vegetables to prevent anaemia and other diseases linked to low iron. Anaemia is a condition where the body does not make enough healthy red blood cells preventing the body’s tissues from getting sufficient oxygen. There is no doubt that iron is a vital element needed for various processes within our body; however, it is important to know that too much iron...

Obesity among adults is a rampant problem worldwide. Being obese means a person has an excessive accumulation of body fat. It can be very dangerous and even life threatening to some. It’s not just being fat. Obesity is a major contributor to preventable, fatal diseases such as high blood pressure, diabetes, cardiovascular disease and more. All of these diseases could have more than likely been prevented if said person took better care of himself or herself. People are consuming too...

Introduction Metabolic syndrome is a cluster of biochemical and physiological abnormalities that occur together, increasing the risk of type 2 diabetes mellitus, stroke and cardiovascular disease (Swarup et. al., 2019). There is growing interest surrounding metabolic syndrome due to the current obesity crisis; it is estimated that as much as 1/3 of the US has metabolic syndrome, both diagnosed and undiagnosed (Saklayen et. al., 2018). Sleep is often overlooked but there is emerging evidence that sleep has a key role...
