During active transport proteins powered by ATP move substances up a concentration gradient. During active transport, a protein pump uses energy, in the form of ATP, to move molecules from an area of low concentration to an area of high concentration. An example of active transport is the sodium-potassium pump, which moves sodium ions to the outside of the cell and potassium ions to the inside of the cell.
Answer:
Texture indicates the relative content of particles of various sizes, such as sand, silt and clay in the soil. Texture influences the ease with which soil can be worked, the amount of water and air it holds, and the rate at which water can enter and move through soil.
Amino acids that must be obtained from foods in order for the body to function properly are called <u>essential amino acids.</u>
<u></u>
- The body is unable to produce essential amino acids. They must therefore originate from food.
- Organic substances known as amino acids are primarily made up of nitrogen, carbon, hydrogen, and oxygen.
- Twenty distinct amino acids are required by your body for growth and optimal operation. Despite the fact that all 20 of these are crucial for your health, just nine are considered essential.
- These include <u>valine, tryptophan, isoleucine, leucine, lysine, methionine, phenylalanine, and threonine.</u>
- While your body may produce non-essential amino acids, it is unable to produce essential amino acids; therefore, you must obtain them through diet.
- Animal proteins including meat, eggs, and poultry are the richest providers of necessary amino acids.
- But some plant meals, such edamame and tofu made from soy, do contain all nine essential amino acids. They are "complete" sources of protein.
