cells need vitamins to use energy. They are used as the building blocks of other cell parts and with enzyms for chemical processess "Food is of no use to our body until we have allowed the cells of our body to convert the food energy (organic energy) into chemical energy through respiration. Cell respiration is when organic material (the food we eat) is converted into chemical energy within the cells to provide the energy we use to perform our everyday activities. Chemical energy is stored within the bonds between carbon and hydrogen. Every time a bond is broken energy is released due to the exothermic reaction that takes place, that is, energy is given to the body. Glucose is a good energy store because of the six carbon-hydrogen bonds. However, the main source of energy is one that is produced within our body. It is the universal energy carrier, ATP, formally known as adenosine triphosphate". Digestion is a complex process. The cells that line the digestive tract secrete into the lumen of the gut a variety of substances, such as hydrochloric acid and digestive enzymes, to break down food molecules into simpler nutrients. The cells absorb these nutrients from the gut lumen, process them, and then release them into the blood for utilization by other cells of the body. All of these activities are adjusted according to the composition of the food consumed and the levels of metabolites in the circulation. The first step in the metabolism of digestible carbohydrate is the conversion of the higher polymers to simpler, soluble forms that can be transported across the intestinal wall and delivered to the tissues. The breakdown of sugars begins in the mouth. Saliva is slightly acidic and contains lingual amylase that begins the digestion of carbohydrates. Once the food has arrived in the stomach, acid hydrolysis contributes to its degradation; specific gastric proteases and lipases aid this process for proteins and fats, respectively. The mixture of gastric secretions, saliva, and food, known collectively as chyme, moves to the small intestine. The resultant glucose and other simple carbohydrates are transported across the intestinal wall to the hepatic portal vein and then to parenchymal liver cells and other tissues. There they are converted to fatty acids, amino acids, and glycogen, or else oxidized by the various catabolic pathways of cells. Most of these pathways are in the mitochondria, whose outer membrane forms an aqueous channel through which proteins up to 10,000 daltons can pass and go into the intermembrane space. The average person's body contains enough glycogen to provide energy for 6-12 hours. In contrast to this, it contains enough fat to provide energy for up to 40 days. An adult man produces enough heat every day during the metabolism of energy, to boil almost 40l of water Energy is also required to enable these digestive and metabolic processes. Between 5% and 10% of the energy that is available in the body is required for metabolising food. Various factors play a role in the generation, storage and utilisation of energy, and include the body's surface-area, age, gender, thyroid hormones, dopamine, serotonin, adrenaline, body temperature and women's menstrual cycle
2 MAJOR PATHWAYS OF ENERGY METABOLISM Glucose is oxidised by all tissues to synthesise ATP. The first pathway which begins the complete oxidation of glucose is called glycolysis. The normal pathways are briefly described 1 Glycolysis 2 Gluconeogenesis 3 The Pyruvate Dehydrogenase Complex 4 The Citric Acid Cycle (Krebs Cycle) 5 Electron Transport and Oxidative Phosphorylation 6 The Pentose Phosphate Pathway 7 Beta-Oxidation of Fatty Acids (With permission from Theo Verwey from his book - NAD Therapy too good to be True- http://www.nutrimalaika.net)
Vitamins play a crucial role in metabolism by acting as coenzymes that help enzymes carry out chemical reactions in the body. They are necessary for the breakdown of macronutrients like carbohydrates, fats, and proteins to produce energy. Vitamins also support various metabolic processes, such as the synthesis of hormones and neurotransmitters.

What B-complex vitamins is involved in the metabolism of fatty acids?
Vitamin B5, also known as pantothenic acid, is involved in the metabolism of fatty acids. It is a key component of coenzyme A, which plays a central role in the breakdown of fatty acids for energy production.
Which structure is home to bacteria that produce vitamins as by products of their metabolism?
The gut microbiota, specifically the large intestine, is home to bacteria that produce vitamins as byproducts of their metabolism. These vitamins include vitamin K and some B vitamins like biotin and folate.
Energy needed for metabolism does not come from?
Energy needed for metabolism does not come from vitamins. Vitamins are essential nutrients that support various bodily functions and processes, but they do not provide energy directly. Energy for metabolism usually comes from macronutrients such as carbohydrates, fats, and proteins.
How is vitamin B helpful?
B Vitamins are 8 water soluble vitamins that play important roles in the cell metabolism
Does vitamins help your body use carbohydrates?
Vitamins play a role in helping your body metabolize carbohydrates into energy. For example, B vitamins such as thiamine, riboflavin, and niacin are essential for converting carbohydrates into usable energy. Adequate vitamin intake is important for overall carbohydrate metabolism and energy production in the body.
Which vitamins plays an important role in calcium and phosphorus metabolism in body?
vitamin d
Would it be good to take vitamins to help a slowing heart?
Vitamins would be helpful to take for a general healthy diet. Vitamins play a crucial role in regulating metabolism, cell health, and heart and organ health.
Do vitamins provide energy?
Vitamins themselves do not provide energy as they do not contain calories. However, vitamins play a crucial role in energy metabolism by helping the body convert nutrients into usable energy. Eating a balanced diet with sufficient vitamins can support overall energy levels in the body.
What benefits does vitamin B 1 6 12 have?
The B vitamins generally have a positive role in energy metabolism. Proper levels of B vitamins in your diet is necessary for proper digestion and the utilization of calories consumed.
Does vitamin b6 and b12 speed your metabolism?
A multivitamin might not necessarily increase your metabolism, but vitamin B is known to help speed up that process. You can often feel more energetic when you take vitamin B and eat a healthy diet.
What is vitamins aminoflex?
Vitamins aminoflex are very important in metabolism and are designed to help in weight loss.
Which describe the role of vatimins?
Vitamins are essential nutrients that play a crucial role in various bodily functions, such as metabolism, immunity, and overall well-being. They help the body to function properly and are necessary for growth, development, and maintenance of good health. Different vitamins serve different functions in the body, so it's important to have a balanced and varied diet to ensure adequate intake of all essential vitamins.
List three vital body processes that vitamins help regulate?
Three vital body processes that vitamins help regulate are digestion, absobtion, and metabolism.
What B-complex vitamins is involved in the metabolism of fatty acids?
Vitamin B5, also known as pantothenic acid, is involved in the metabolism of fatty acids. It is a key component of coenzyme A, which plays a central role in the breakdown of fatty acids for energy production.
