What is the relationship between energy and photosynthesis?

The main purpose of photosynthesis is to convert radiant energy from the sun into chemical energy that can be used for food. Cellular respiration is the process that occurs in the mitochondria of organisms (animals and plants) to break down sugar in the presence of oxygen to release energy in the form of ATP.

What is the relationship between photosynthesis and humans?

Humans are reliant on photosynthesis to produce the food that we eat, as a source of energy to create heat, light and electricity and for many of the materials that we make and use in our everyday lives.

Is photosynthesis an example of energy coupling?

Photosynthesis represents a good example of energy coupling, as energy from sunlight is coupled to reactions in chloroplasts so that the reactions can unfold.

What type of energy is needed for photosynthesis to happen?

Photosynthesis is the process in which light energy is converted to chemical energy in the form of sugars. In a process driven by light energy, glucose molecules (or other sugars) are constructed from water and carbon dioxide, and oxygen is released as a byproduct.

What energy transformation occurs in photosynthesis?

Description. Photosynthesis is the process by which energy is converted to chemical energy in plant cells.

Where does the energy for photosynthesis come from?

During the process of photosynthesis, cells use carbon dioxide and energy from the Sun to make sugar molecules and oxygen. These sugar molecules are the basis for more complex molecules made by the photosynthetic cell, such as glucose.

Does photosynthesis release energy?

In photosynthesis, solar energy is harvested and converted to chemical energy in the form of glucose using water and carbon dioxide. Oxygen is released as a byproduct.

How are humans and plants connected?

Photosynthesis and respiration are the two essential processes that allow life to sustain on earth. In a way, they are a cycle — plants help humans breathe by providing us with oxygen, and humans help plants “breathe” by providing them with carbon dioxide.

What is an example of a coupled reaction in photosynthesis?

So, the glucose and O2 created by photosynthesis is used in respiration to make CO2 and water – the materials needed in photosynthesis. In this way, these two reactions are coupled.

How are the reactions of photosynthesis and cellular respiration interconnected?

Photosynthesis makes the glucose that is used in cellular respiration to make ATP. The glucose is then turned back into carbon dioxide, which is used in photosynthesis. While water is broken down to form oxygen during photosynthesis, in cellular respiration oxygen is combined with hydrogen to form water.

What form of energy do plants give when you eat them?

Most of this energy is stored in compounds called carbohydrates. The plants convert a tiny amount of the light they receive into food energy. When animals eat green plants (2) they consume and absorb some of this energy, which stored as chemical energy in compounds known as fats and protein.
