The Elements of Life

In biology, the elements of life are the essential building blocks that make up living things. They are carbon, hydrogen, nitrogen, oxygen, phosphorus, and sulfur. The first four of these are the most important, as they are used to construct the molecules that are necessary to make up living cells. These elements form the basic building blocks of the major macromolecules of life, including carbohydrates, lipids, nucleic acids and proteins. Carbon is an important element for all living organisms, as it is used to construct the basic building blocks of life, such as carbohydrates, lipids, and nucleic acids. Even the cell membranes are made of proteins. Carbon is also used to construct the energy-rich molecules adenosine triphosphate (ATP) and guanosine triphosphate (GTP). Hydrogen is used to construct the molecules water and organic compounds with carbon. Hydrogen is also used to construct ATP and GTP. Nitrogen is used to construct the basic building blocks of life, such as amino acids, nucleic acids, and proteins. It is also used to construct ATP and GTP. Oxygen is used to construct the basic building blocks of life, such as carbohydrates, lipids, and nucleic acids. It is also used to construct ATP and GTP. Phosphorus is used to construct the basic building blocks of life, such as carbohydrates, lipids, and nucleic acids.

What is associated with photosystem 1?

Photosystem I is an integral membrane protein complex that uses light energy to catalyze the transfer of electrons across the thylakoid membrane from plastocyanin to ferredoxin. Ultimately, the electrons that are transferred by Photosystem I are used to produce the moderate-energy hydrogen carrier NADPH.

Which of the following are directly associated with photosystem first?

Excited electrons leave the Photosystem I reaction-center chlorophyll and are taken up by an electron acceptor, which passes them down an electron transport system before they return to Photosystem I.

What does photosystem 1 do in photosynthesis?

Photosystem I (PSI) of photosynthesis (Fig. 1) provides energy to reduce NADP to NADPH, which is required for carbon fixation and other synthetic processes.

What are the steps of photosystem 1?

ATP is produced on the stromal side of the thylakoid membrane, so it is released into the stroma. The electron arrives at photosystem I and joins the P700 special pair of chlorophylls in the reaction center..
