What is used to break down oxygen and hydrogen?

This is the formation of hydrogen gas. Every water molecule includes two atoms of hydrogen and one atom of oxygen. We use a process called electrolysis to break apart water molecules into hydrogen and oxygen. Electrolysis uses an electrical current to split the molecule apart.

What is used to break down water in photosynthesis?

For over three billion years, nature has been using sunlight as its primary energy source in photosynthesis. In the course of this process, plants, algae and cyanobacteria (blue-green algae) use sunlight to split water and produce energy-rich chemical compounds from carbon dioxide (CO2).

What are oxygen and hydrogen used for in photosynthesis?

In the first reaction, energy is used to split water molecules into hydrogen and oxygen. The hydrogen is needed for the second stage of reactions and the oxygen is released by the plant as a waste product. In the reactions of the second stage, the hydrogen is combined with carbon dioxide to make glucose.

Is oxygen used in photosynthesis?

In photosynthesis, solar energy is harvested as chemical energy in a process that converts water and carbon dioxide to glucose. Oxygen is released as a byproduct. In cellular respiration, oxygen is used to break down glucose, releasing chemical energy and heat in the process.

Why is oxygen important for respiration?

Cellular respiration is the cellular process which transfers chemical energy from glucose to ATP. Oxygen is essential to have efficient cellular respiration; most organisms need oxygen for a single purpose: to release energy from food for use by cells.

What are the 3 main steps of aerobic respiration?

Aerobic respiration is divided into three main stages: Glycolysis, Citric acid cycle and Electron transport chain.

What occurs during glycolysis?

Glycolysis is the process in which one glucose molecule is broken down to form two molecules of pyruvic acid (also called pyruvate). During the latter stages of glycolysis, four ATP molecules are synthesized using the energy given off during the chemical reactions.
