Adipose triacylglycerols contain the largest amount of stored energy in humans, followed by protein (even though loss of too much protein will lead to death), muscle glycogen, and liver glycogen.

What is the function of pepsin in the stomach quizlet?
What is the function of the pepsin? It degrades food protein into peptides . Begins the chemical digestion of a protein.
What is the importance of consuming an adequate amount of protein quizlet?
What is the importance of consuming an adequate amount of proteins in the diet? 1. They are used as cofactors for metabolic reactions and are required in minute quantities.
Whats is the body’s main source of energy?
Your body breaks down carbohydrates into glucose. Glucose, or blood sugar, is the main source of energy for your body's cells, tissues, and organs. Glucose can be used immediately or stored in the liver and muscles for later use.
Is are the main source of the body’s energy?
Carbohydrates are the main energy source of the human diet.

What makes lipid A better source of energy compared to carbohydrates?
Because one triglyceride molecule yields three fatty acid molecules with as much as 16 or more carbons in each one, fat molecules yield more energy than carbohydrates and are an important source of energy for the human body.
What is the substance found in the stomach that allows for chemical digestion to take place?
Pepsin Pearls Pepsin is a stomach enzyme that serves to digest proteins found in ingested food. Gastric chief cells secrete pepsin as an inactive zymogen called pepsinogen. Parietal cells within the stomach lining secrete hydrochloric acid that lowers the pH of the stomach.
What is the role of pepsin in protein digestion?
Of these five components, pepsin is the principal enzyme involved in protein digestion. It breaks down proteins into smaller peptides and amino acids that can be easily absorbed in the small intestine.
What effect does dietary protein have on the body quizlet?
Proteins build muscle mass and contour; facilitate hair, nails and bone growth; regulate energy levels; and support chemical processes within the body which include enzyme, hormone and antibody production.
What is the importance of consuming an adequate amount of proteins in a diet?
The basic structure of protein is a chain of amino acids. You need protein in your diet to help your body repair cells and make new ones. Protein is also important for growth and development in children, teens, and pregnant women.
What stores the most energy in your body?
Fat is the body's most concentrated source of energy, providing more than twice as much potential energy as carbohydrate or protein (9 calories per gram versus 4 calories each per gram). During exercise, stored fat in the body (in the form of triglycerides in adipose or fat tissue) is broken down into fatty acids.
Where is energy stored in the body?
Energy is actually stored in your liver and muscle cells and readily available as glycogen. We know this as carbohydrate energy. When carbohydrate energy is needed, glycogen is converted into glucose for use by the muscle cells. Another source of fuel for the body is protein, but is rarely a significant source of fuel.
What is the best source of energy for the body?
Carbohydrates Carbohydrates are the main energy source of the human diet. The metabolic disposal of dietary carbohydrates is direct oxidation in various tissues, glycogen synthesis (in liver and muscles), and hepatic de novo lipogenesis.
Which nutrient is the richest source of energy and why?
Grains — along with fruits, vegetables, and dairy — contain carbohydrates, the body's main source of energy.
Which gives more energy carbohydrates or fats?
Fat has more than twice as many calories per gram as carbohydrates and proteins. A gram of fat has about 9 calories, while a gram of carbohydrate or protein has about 4 calories. In other words, you could eat twice as much carbohydrates or proteins as fat for the same amount of calories.
Why fat is the richest source of energy?
Each gram of fat supplies the body with about 9 calories, more than twice that supplied by proteins or carbohydrates. Because fats are such an efficient form of energy, the body stores any excess energy as fat.
Why lipids store more energy?
Greater number of electrons around carbon atoms in fatty acids are shifted to oxygen, more energy is liberated than when the same process occurs to carbohydrates.
Where does most of the work of chemical digestion take place?
the small intestine The majority of chemical digestion occurs in the small intestine. Digested chyme from the stomach passes through the pylorus and into the duodenum. Here, chyme will mix with secretions from both the pancreas and the duodenum.
What is called chemical digestion?
This is the process where complex molecules like proteins, fats, and carbohydrates are broken down into smaller pieces that your body can use. It requires special proteins called enzymes. Movements. There are many movements that keep food going through your digestive system.
What is pepsin and pepsinogen?
Pepsin is a stomach enzyme that serves to digest proteins found in ingested food. Gastric chief cells secrete pepsin as an inactive zymogen called pepsinogen. Parietal cells within the stomach lining secrete hydrochloric acid that lowers the pH of the stomach. A low pH (1.5 to 2) activates pepsin.
What is pepsin and trypsin?
Pepsin is an enzyme which acts only in acidic medium ,trypsine is an enzyme which acts in alkaline medium. pepsin is secreted by gastric juice, trypsin secreted by pancreatic juice. Pepsin is secreted in stomach, trypsin is secreted in small intestine.
What role does protein play in the body quizlet?
What roles do proteins play in the body? Provide energy, structure & mechanical support & help maintain body tissue, build enzymes/hormones, maintain body fluid & acid-base balance.
How does the cell use amino acids as an energy source quizlet?
Amino acids are used to make nonprotein molecules that contain nitrogen, such as DNA, RNA, and neurotransmitters. – In order for the body to use amino acids as an energy source, the nitrogen-containing amino group must be removed (deamination) and converted into urea which goes to the kidneys for removal.
Which of the following is rich source of protein?
eggs. dairy products – milk, yoghurt (especially Greek yoghurt), cheese (especially cottage cheese) nuts (including nut pastes) and seeds – almonds, pine nuts, walnuts, macadamias, hazelnuts, cashews, pumpkin seeds, sesame seeds, sunflower seeds. legumes and beans – all beans, lentils, chickpeas, split peas, tofu.
How can I gain weight female?
Eat five to six smaller meals during the day rather than two or three large meals. Choose nutrient-rich foods. As part of an overall healthy diet, choose whole-grain breads, pastas and cereals; fruits and vegetables; dairy products; lean protein sources; and nuts and seeds. Try smoothies and shakes.
What is stored energy in the body?
ATP is also known as the energy currency of the body, because all energy is stored in the form of ATP, and the stored energy is released by the breakdown of ATP, the released energy is used by muscles and other parts of the body.
What is the main source of energy of the human body?
Carbohydrates Abstract. Carbohydrates are the main energy source of the human diet. The metabolic disposal of dietary carbohydrates is direct oxidation in various tissues, glycogen synthesis (in liver and muscles), and hepatic de novo lipogenesis.
What helps the body store energy?
Insulin helps our bodies store extra glucose For example, if you eat a large meal and your body doesn't need that much glucose right away, insulin will help your body store it to convert to energy later. Insulin does this by turning the extra food into larger packages of glucose called glycogen.
