The correct answer is Carbohydrates.
Carbohydrates are organic compounds consisting of carbon, hydrogen and oxygen present in all living organisms. They are the main source of energy for the body and are also used to build and repair tissues.
Proteins are organic compounds consisting of carbon, hydrogen, oxygen, and nitrogen. They are essential for the growth and repair of tissues, and for the production of enzymes, hormones, and antibodies.
Fats are organic compounds consisting of carbon, hydrogen, and oxygen. They are a source of energy for the body, and are also used to build and repair tissues.
Minerals are inorganic substances that are essential for the proper functioning of the body. They are found in the blood, bones, and other tissues.
Here is a more detailed explanation of each option:
- Proteins are organic compounds consisting of carbon, hydrogen, oxygen, and nitrogen. They are essential for the growth and repair of tissues, and for the production of enzymes, hormones, and antibodies. Proteins are made up of amino acids, which are the building blocks of proteins. There are 20 different types of amino acids, and the human body can produce 11 of them. The other 9 amino acids must be obtained from food. Proteins are found in all living things, and they play a vital role in many different processes in the body.
- Carbohydrates are organic compounds consisting of carbon, hydrogen, and oxygen. They are the main source of energy for the body and are also used to build and repair tissues. Carbohydrates are made up of sugar molecules, which are linked together in different ways. There are three main types of carbohydrates: simple carbohydrates, complex carbohydrates, and fiber. Simple carbohydrates are made up of one or two sugar molecules. They are found in foods like sugar, honey, and fruit juice. Complex carbohydrates are made up of many sugar molecules. They are found in foods like bread, pasta, rice, and potatoes. Fiber is a type of complex carbohydrate that the body cannot digest. It is found in foods like fruits, vegetables, and whole grains.
- Fats are organic compounds consisting of carbon, hydrogen, and oxygen. They are a source of energy for the body, and are also used to build and repair tissues. Fats are made up of fatty acids, which are the building blocks of fats. There are two main types of fatty acids: saturated fatty acids and unsaturated fatty acids. Saturated fatty acids are found in animal products like meat, dairy, and eggs. Unsaturated fatty acids are found in plant-based foods like vegetable oils, nuts, and seeds.
- Minerals are inorganic substances that are essential for the proper functioning of the body. They are found in the blood, bones, and other tissues. Minerals are needed for many different processes in the body, including metabolism, nerve function, and muscle contraction. There are many different types of minerals, and each one plays a different role in the body. Some of the most important minerals include calcium, iron, magnesium, potassium, and sodium.
