I Am A Marine Biologist, And This Has Been My Dream Since I

I’ve always had a keen interest in science. When I was younger, I viewed a dolphin show online. I was instantly fanisnated and later I was informed that the trainers were special marine biologists. The idea of becoming a marine biologist is still a dominate career choice for me. Last year, I was incredibly curious with the aspects that a marine biologist has to undertake that I researched the career path as part of my PLP. This only ignited my interest even further and when I was invited to attend the Flinders University I particularly focused on the marine biology and biology lectures.

After graduating high school, I was accepted to Alabama State University and decided to study Biology. I figured that this area would help me study living organisms, life processes and understanding the basic life processes that required different medical provisions. I believed that I would eventually find out if I wanted to studying medicine or counsel people. On May 7, 2011, I graduated from Alabama State University with my Bachelor’s degree in Biology. Then I volunteered at Jamaica Hospital emergency room alongside the medical providers and interact with the families of those who are medically

Homeostatic is all about balance so when you begin to exercise, you need more oxygen. The harder you breathe the more energy it takes to replace it. Your body temperature while exercising also increases; typically it creates too much heat so your body has to figure out a way to release the heat so it doesn't become dangerous. This is done by sweating

Exercise increases the use of energy by your muscles, which activates a series of reactions to create new energy to keep exercising and maintain homeostasis. The first reaction that occurs is an increase in your breathing rate. Energy creation requires significant oxygen. The only way to provide the necessary oxygen is to increase the speed at which your respiratory system is introducing it into your bloodstream. The harder you exercise, the more energy is used, resulting in your body increasing your breathing rate even more to maintain adequate energy levels for balance.

The energy for all physical activity comes from the conversion of high-energy phosphates (adenosine triphosphate—ATP) to

Metabolism comprises of a vital set of biochemical reactions that all living organisms require to sustain life. For a marathon runner, their physiological response to strenuous exercise depletes both their fats and carbohydrate storage in order to supply energy in the form of Adenosine Triphosphate (ATP). ATP is the energy form that the human body uses for biological processes such as movement and synthesis of biomacromolecules. In regards to running a marathon, the athlete is capable of using a combination of both anaerobic and aerobic pathways, but these different systems predominate at different intervals in order to increase the energy allowed for the muscles.

One must be able to understand the changes that the human body goes through to determine cause of death. Some of the classes that my major requires are biology of animals, biology of the cell, as well as chemistry. These classes are intended to make a student with interest in biology familiar with what he or she may see in their actual career. In my case, I will see all three. Most of these classes also have laboratory classes that coincide with them to familiarize students with the environment that he or she may be in. While most of the time, these classes can be exciting, they are not easy. Having a biology major requires dedication and diligence in order to complete the many years of school that it entails.

The metabolic process providing my energy while I was walking at an easy pace is aerobic metabolism. During aerobic metabolism, mitochondria absorb from the surrounding cytoplasm these molecules: ADP, phosphate ions, O2, and organic substances like pyruvate. These molecules go through the citric acid cycle. The electron transport chain is also involved to create ATP. For each molecule of pyruvate that goes into the citric acid cycle, the cell gains 17 ATP molecules. Glycogen reserves can also be used and converted to glucose. Glycolysis breaks down glucose

Introduction: Exercise is a physical activity or particular movement that is used in order to become healthier and stronger. (1) Exercise, in all of its forms, has various effects on the different systems in the human body. One of the main benefits is cardiovascular health, including circulation and heart health. Exercise uses a lot of energy, which the cells derive from oxidising glucose. Meaning that the heart has to work harder to pump more blood throughout the body and the heart has to beat faster in order to achieve a high effort. (2) The heart benefits from exercise include being able to pump more blood through the body and continue working at a higher level with less strain. (3)

However, if intense physical demands such as cycling, swimming or running are placed on the body, the systems respond by producing much higher levels of ATP to ensure that our immediate energy needs are met. When doing these exercises ATP then becomes ADP, as there is a loss in the phosphate molecules. The body has two main energy systems, the aerobic energy system which utilises fats, carbohydrate and sometimes proteins for re-synthesising ATP for energy use.

It needs more energy and oxygenated blood because body cell lacks oxygen due to most of the oxygen entering the brain to prevent us from being unconscious and blacking out. It also prevents CO2 to release from our body and cause it to increase/build up because of the absence of O2. Therefore, the body becomes more efficient at utilizing oxygen during and after exercise to maintain homeostasis which expands our lungs more than usual and helps us inhale and exhale as much as air possible. This results in an increase in vital capacity. The heart rate also speeds up which also increase breathing because the lung and heart work together to create gas exchange using simple diffusion from the assistance of capillaries and transport oxygenated blood to tissues throughout the body.

Whether it is picking up a glass of water or running a marathon, when you are doing any type of activity your body needs energy. Energy is the strength you sustain when doing a physical or mental activity. If it wasnt for that you would be laying on a couch barely breathing. Though, in order for our bodies to get the amount of energy we need we need cellular respiration to occur. Cellular respiration is when the cells take action is turning biochemical energy from the food we eat and turn it into chemical energy for us to use during activities.

My personal goal in my educational career is to achieve a major in Genetics and a minor in Marine Biology. To strive closer to accomplishing this goal, I am currently enrolled in my high school’s Career and Technical Education (CTE) of Marine Biology. Over the past three years, I have been working on my own research project, Survival and Growth Performance of Crassostrea virginica in the NYC Harbor; comparing two types of spawning methods of the Eastern Oyster, which I presented at the New York City Science and Engineering Fair, and was awarded The National Oceanic and Atmospheric Administration (NOAA) Taking the Pulse of the Planet Award. On peaceful days, I manage the lab and its 15 tanks ranging from Mollies to Tilapia. After School, I

Oxygen is required by the cells to carry out respiration, this provides the energy in the form of adenosine-triphosphate (ATP) which is a molecule required for muscular contraction. As exercise takes place, oxygen is used

But a small quantity of ATP is socked away in your muscles for when you need to expend a short burst of energy in a hurry. Let’s say you’re doing a single barbell squat with close to max weight. As you power the weight up, the muscles of your hips, thighs and lower back immediately burn through their ATP stores. Once the ATP has done its job, it’s either further broken down or recycled (with the help of another substance, creatine phosphate, or CP), so it can provide more energy to your working muscles.
