1. Janine and Mitchell were talking about carbohydrates and proteins. Proteins are large and complex molecules that play many roles in the body. Our body contains many cells that are responsible for a specific job. Proteins do most of the work in cells that are required for the structure, function, and regulation of the body 's tissues and organs. In each cell there is a lot of proteins that work together like a machine to run each cell, just like the engine in a car proteins look different and they all have different tasks that allow the engine to run. Proteins are made of amino acids that are attached to one another in a long chain. Proteins are needed for mechanical support(a fibrous protein), and also needed for immune …show more content…
2. The nervous system has a structural unit called the neurone, which is a cell in its cytoplasm containing a lot of mitochondria. Neurone produces the energy by cellular respiration and uses glucose as a substratum. Janine is not right because it doesn 't get you mad you can be without carbohydrates but you do get really tired.
3. Janine was wrong because studies have said that there is no evidence that supports the idea that if you intake to much protein it can cause kidney damage. Proteins do not have no negative impact on kidneys. The metabolism consist of the constructive phase and the destructive phase, in which complex materials are broken down. Transformation of carbohydrates, fats, and proteins in food to energy, are parts of the metabolism.
4. Calories are units by which energy is measured. Energy is the capacity to do work. The energy in food is chemical energy. The body can convert the chemical energy to mechanical, electrical, and heat energy. A calorie free energy drink would be misleading because calories is what they use to measure the units of energy needed. Calories is the energy in the energy drink and if it has no calories then it would have no energy, which would not be considered an energy drink anymore.
5. The substances that supply energy to the human body would be organic nutrients that include carbohydrates, fats, proteins, and vitamins. Pg.4
1. Obesity and overweight are about the same thing. They are both
1.protein regulate body process -Proteins are also enzymes which help digst or break down the food we eat. our body digest protein into amino acids component and reassemble them into ur body. Protein also forms our human blood which carries oxygen into our cells.
Energy metabolism is where the nutrients oxygen and glucose are took in and delivered the organs. Energy is needed in order for our body to be able to function. Energy helps break down molecules and to build new molecules.
5. Which substances supply energy to the human body? Answer: Water, vitamins, carbohydrates, minerals, proteins, and lipids.
Carbohydrates are composed of carbon, hydrogen, and oxygen. Carbohydrates can come from fruits, vegetables, and grains. There are two different kinds of carbohydrates. The first being simple carbohydrates, which are sugars. Glucose, fructose, and galactose fall under the sugar category. Then you have your complex carbohydrates, which are starch in grains, glycogen stored in our muscles, and fiber. When it comes to energy within our body glucose is a major source of energy. When our body does not get enough carbohydrates to supply enough glucose, our body will make glucose from proteins. I applied this to my life by making sure I eat fruits, vegetables, and grains to get my carbohydrates every single
The energy release from glucose or ATP during a chemical reaction is an example of chemical energy. This energy it is used for making proteins, making muscles to move, for heat and hormones.
There are many types of foods, nutrients, and minerals that are important to the body, and the ones that will be covered in this paper are electrolytes, carbohydrates, and proteins. The items listed above are vital to body functions in many ways; for example, electrolytes necessary for proper muscle contraction (Nordqvist 2013). Proteins are essentially what allow our bodies to function as they do, and carbohydrates provide us with the energy that allows it to function. Our body is an amazing and intricate machine, and that’s basically what it is -- a well-oiled machine. In this adventure we will discover what makes our bodies work the way they do, what moves the figurative cogs of our body, and what makes us tick inside.
Proteins are polymeric chains that are built from monomers called amino acids. All structural and functional properties of proteins derive from the chemical properties of the polypeptide chain. There are four levels of protein structural organization: primary, secondary, tertiary, and quaternary. Primary structure is defined as the linear sequence of amino acids in a polypeptide chain. The secondary structure refers to certain regular geometric figures of the chain. Tertiary structure results from long-range contacts within the chain. The quaternary structure is the organization of protein subunits, or two or more independent polypeptide chains.
Carbohydrate is a nutrient essential for energy production and the prevention of ketosis, a state where the production of ketones exceeds metabolism. Protein is a nutrient essential for its components, amino acids. Fat is a nutrient which provides insulation, protection and energy for the body.
Proteins cannot be stored except in eggs and seeds and they form the body's main structural elements and are found in every cell and tissue. The human body uses proteins for growth and to build and repair bones, muscles, tissue, skin, internal organs and blood. Hormones, antibodies
The macronutrients (excluding fiber and water) provide structural material (amino acids from which proteins are built, and lipids from which cell membranes and some signaling molecules are built) and energy. Some of the structural material can be used to generate
Proteins are one of the key biomolecules that make up the human body and facilitate different processes and reactions in the body (Silverthorn, 2016). Proteins exist in every cell in the human body and there are many different types of proteins with specialized functions that are necessary to maintain homeostasis (Silverthorn, 2016). Enzymes are a type of protein that performs like catalysts in the cells and start specific reactions (Ira, 2009).Catalysts start or increase the rate at
According to Ayoob( 2009), a calorie can be defined as a unit of heat energy that human body use as energy to produce heat. This energy fuels human body for strength in daily activity. In scientific term, there are two types of calories which small calorie and large calorie (Nordqvist, 2013).
1. When we say that something gives us "energy”, what does that mean? What is a biological definition of energy?
Three different metabolic energy systems power your workouts — and your day. Here’s how each one works, and how to make the most of them all.
Some of our energy comes from the foods that we eat and the liquids we drink. Three main nutrients that we use for energy are carbohydrates, protein, and fats. Carbohydrates are the most important source. Your body can also use protein and fats for energy when carbs have been depleted. If you want to lose weight then dieting and exercising will help you to lose weight. Therefore the best way to lose weight is to eat smaller portions, choose healthier foods, and get more exercise. Dana Joy Altman said “Smaller portions, no seconds, more fruit, less bread and cheese, longer walks”.
