Proteins are used for all kinds of structure and function inside cells. Proteins make up structural molecules such as the cytoskeleton that allow cells to move, grow, divide and keep a specific structure to do their job in the body. Proteins also make up enzymes, that perform all the ...
(b) Do we need to eat proteins or can our body make them? Explain. Proteins: Proteins are a long chain of amino acids made up of C, H, N, and O molecules. Protein is an optically active or chiral organic molecule. The cell of all th...

The PcG and TrxG proteins are recruited to cis-regulatory elements called Polycomb/Trithorax response elements (PREs). The PcG and TrxG proteins act antagonistically through PREs to maintain silent and active gene expression states, respectively. These states are initiated by transcription factors that...
Proteins Using the text book, you have 5 minutes to find and write down notes on: What elements are present in proteins? Which element is ESSENTIAL to build proteins Where do (i) plants (ii) animals get this element from? What are the main uses of proteins?
The cell is composed primarily of the elements hydrogen, carbon, oxygen and nitrogen. These molecules make the organic molecules like carbohydrates, proteins, fats, and nucleic acid that make the different parts of the cell. These different parts of the
Protein ingredients, like meat and fish, are often one of the first ingredients pet parents look for when choosing a recipe for their dog. But what is protein for, and how much do dogs really need? Proteins are made up of amino acids, the building blocks of muscle and other tissue; the...
fact that whey is derived from essentially an animal protein source, it inevitably has a high PDCAAS score. Animal proteins are more structurally similar to human proteins than plants are, so our bodies are able to make more efficient use out of animal proteins as opposed to plant proteins. ...
Here are some of its primary functions: Circulating oxygen When you think about what elements are needed to stay alive, oxygen probably comes to mind first. But oxygen can’t sustain life all on its own. Blood carries the oxygen from our lungs to other areas of our body.1 Delivering ...
Importance of Nutrient Cycling All living organisms, biomolecules and cells are made up of carbon, hydrogen, oxygen, nitrogen, sulphur and phosphorus. These elements are essential for life. It is important to recycle and continuously replenish nutrients into the environment for life to exist. ...
