Describe the processes beginning with nutrition which result in the formation of proteins in the leaves of a photosynthetic plant?

Answer 1

I think the reason nobody has answered your question is because it's very, very big, and very long.
a) Leaves use photosynthesis to take light from the sun and carbon dioxide from the air to create the proteins that a plan needs to grow. the light provides the energy necessary to break the carbon dioxide into its component atoms and build proteins from carbon. all life on this planet is carbon based, including plant life, and carbon dioxide is the source of carbon for plants. we eat plants, and use those proteins to grow our own bodies. usually we break down the proteins that plants provide us into their constituent amino acids, and then build them back up into the proteins that we need, since plant proteins and human proteins are different.
b) when we eat things, like plants, the proteins we get from them are broken down into amino acids by the acid in our stomack and intestines. our intestines then absorb the amino acids and use them to build up proteins that are important for humans (muscles, skin cells, hair, you name it). We have enzymes that take the amino acids that we eat and build them up into these proteins.
c) protein in animals serves many, many purposes. the most obvious of which is building muscle. but proteins are involved in almost every human biological process. proteins are involved in all of the signalling mechanisms responsible for keeping us alive - from our heart beat, to processing sugar into energy, to our brains understanding new information and storing it. absolutely everything.
so without plants, from which we get proteins, we wouldn't have the amino acids, which we use to build our own proteins, which govern everything that the human body does
