Answer: 1. (a) Protein: Protein is a macronutrient composed of amino acids, which are organic compounds made of carbon, hydro, nitrogen, oxygen or sulphur. It is needed by the body to build and repair tissues, to make enzymes, hormones, and other body chemicals. Protein is an important building block of bones, muscles, cartilage, skin, and blood. Protein is found in animal, legumes and nuts. Good sources of protein include cowpea,eggs, chicken Breast, cottage cheese, yogurt, milk
(b)Carbohydrate: Carbohydrates are macronutrients that contain carbon, hydrogen and oxygen. Carbohydrate is found in fruits, grains, vegetables and milk products. The functions of carbohydrate include providing energy and regulation of blood glucose, breakdown of fatty acids and prevention of ketosis and provision of dietary fibre. Food sources of carbohydrate are oat, buckwheat, sweet potato, cassava, yam, banana
(c) Fats: Fat are food molecules consisting of carbon and hydrogen. Fats are soluble in organic solvents and insoluble in water. Examples of fats include cholesterol, phospholipids, and triglycerides. Fats give the body energy and support cell growth. They also help protect body organs and help keep the body warm. Fats help the body absorb some nutrients and produce important hormones, too. Foods rich in fats include salmon, avocados, olives, and walnuts, and vegetable oils like soybean, corn, canola, and olive oil, butter and cheese.
2. Janine is right because the brain performs many complicated roles that use up a lot of energy. The brain uses half of the total glucose in the human body. Some of the brain functions such as learning, thinking, learning, and memory are based on the levels of glucose in the brain. However, the levels of glucose in the body should be balanced, High levels cause insulin resistance. Insulin regulates blood sugar. If the brain doesn`t get carbohydrates well, one becomes cranky.
Brain cells need glucose to fuel cellular activities. Glucose metabolism provides the fuel for physiological brain function through the generation of ATP, the foundation for neuronal and non-neuronal cellular maintenance, as well as the generation of neurotransmitters.
(3) Janin is wrong because although excess protein can cause damage in people with preexisting kidney disease, there's been no record of major studies linking high protein intake to kidney damage in healthy individuals.
Cellular respiration is the breakdown of food molecules to release energy in the form of ATP. Carbohydrates, fats, and proteins can all be used as fuels in cellular respiration. The energy released is needed for growth, repair and movement.
(4) Calorie: calorie is a unit of energy. We can get calories from a variety of food sources, such as, fats, proteins, carbohydrates or sugars. Calories can also be said to be the amount of energy released when the body breaks down food.
Energy: this is power derived from the utilization of chemical substances found in food. The body needs energy to function in its optimal state.
The label 'energy free drink' is misleading because it may contain sugar alcohol such as sorbitol or mannitol which is not calorie-free and may cause digestive upset.
(5) Carbohydrates, fats and proteins supply energy to the human body.
1. (a) Protein: Protein is a macronutrient composed of amino acids, that are natural compounds made from carbon, hydro, nitrogen, oxygen, or sulfur. It is wanted with the aid of using the frame to construct and restore tissues, to make enzymes, hormones, and different frame chemicals. Protein is a critical constructing block of bones, muscles, cartilage, skin, and blood. Protein is determined in animals, legumes, and nuts. Good assets of protein consist of cowpea, eggs, chook Breast, cottage cheese, yogurt, milk
(b) Carbohydrates: Carbohydrates are macronutrients that incorporate carbon, hydrogen, and oxygen. Carbohydrate is determined in fruits, grains, veggies, and milk products. The features of carbohydrates consist of imparting electricity and law of blood glucose, breakdown of fatty acids and prevention of ketosis and provision nutritional fiber. Food reasserts of carbohydrates are oat, buckwheat, candy potato, cassava, yam, banana
(c) Fats: Fat is meals molecules that include carbon and hydrogen. Fats are soluble in natural solvents and insoluble in water. Examples of fat consist of cholesterol, phospholipids, and triglycerides. Fats provide the frame electricity and aid cellular growth. They additionally assist shield frame organs and assist in maintaining the frame warm. Fats assist the frame to soak up a few vitamins and convey critical hormones, too. Foods wealthy in fat consist of salmon, avocados, olives, walnuts, vegetable oils like soybean, corn, canola and olive oil, butter, and cheese.
2. Janine is proper due to the fact the mind plays many complex roles that expend quite a few electricity. The mind makes use of 1/2 of the whole glucose withinside the human frame. Some of the mind's features along with learning, thinking, learning, and reminiscence are primarily based totally on the stages of glucose withinside the mind. However, the stages of glucose withinside the frame ought to be balanced, High stages purpose insulin resistance. Insulin regulates blood sugar. If the mind does not get carbohydrates well, one will become cranky.
(3) Janin is inaccurate due to fact despite the fact that extra protein can purpose harm in humans with preexisting kidney disease, there is been no document of predominant research linking excessive protein consumption to kidney harm in healthful individuals.
Cellular respiratory is the breakdown of meals molecules to launch electricity withinside the shape of ATP. Carbohydrates, fat, and proteins can all be used as fuels in mobile respiratory. The electricity launched is wanted for growth, restoration, and movement.
(4) Calorie: a calorie is a unit of electricity. We can get energy from lots of meal reasserts, along with, fat, proteins, carbohydrates, or sugars. Calories also can be stated to be the quantity of electricity launched while the frame breaks down meals.
Energy: that is strength derived from the usage of chemical materials determined in meals. The frame desires electricity to be characteristic of its most excellent state.
The label 'electricity unfastened drink' is deceptive due to the fact it is able to incorporate sugar alcohol along with sorbitol or mannitol which isn't calorie-unfastened and might purpose diges.
5) Carbohydrates, fat, and proteins deliver electricity to the human frame
What are nutrients?
Nutrient. Nutrients are chemicals in meals that can be utilized by the frame to feature well and hold health. Examples encompass proteins, fats, carbohydrates, vitamins, and minerals.
Hence concluded that all the above answers are correct.
