What is the link between photosynthesis and respiration?

Photosynthesis converts carbon dioxide and water into oxygen and glucose. Glucose is used as food by the plant and oxygen is a by-product. Cellular respiration converts oxygen and glucose into water and carbon dioxide. Water and carbon dioxide are by- products and ATP is energy that is transformed from the process.

What is respiration photosynthesis?

Photosynthesis is the process by which plants use light energy to convert carbon dioxide and water into sugars. Respiration occurs when glucose (sugar produced during photosynthesis) combines with oxygen to produce useable cellular energy. This energy is used to fuel growth and all of the normal cellular functions.

What are the similarities of cellular respiration and photosynthesis?

Some differences between photosynthesis and respiration are that photosynthesis only happens in sunlight while respiration happens constantly and that photosynthesis releases oxygen while respiration uses it. Some similarities between the two are that both produce energy and involve the exchange of gases.

Why do photosynthesis and respiration couple together?

Cellular respiration is a complex set of enzyme-catalyzed reactions that break apart glucose, making 6 molecules of CO2 along the way. 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.

Which occurs in the presence of oxygen?

aerobic respiration
Cellular respiration that proceeds in the presence of oxygen is called aerobic respiration.

Does respiration occur in plants?

Plant cells respire, just as animal cells do. If they stop respiring, they will die. aerobic respiration uses oxygen and produces carbon dioxide.

Do plants take in oxygen at night?

During daylight hours, plants take in carbon dioxide and release oxygen through photosynthesis, and at night only about half that carbon is then released through respiration. However, plants still remain a net carbon sink, meaning they absorb more than they emit.

Do plants breathe oxygen?

Most folks have learned that plants take up carbon dioxide from the air (to be used in photosynthesis) and produce oxygen (as a by-product of that process), but less well known is that plants also need oxygen. So plants need to breathe — to exchange these gases between the outside and the inside of the organism.

What are the similarities between cellular respiration and respiration?

Both processes involve taking in oxygen and removing carbon dioxide, and we need both to survive. However, breathing is a macroscopic process and only ships the oxygen and carbon dioxide around the body. Cellular respiration is a microscopic process, taking place in the cells.

What are the similarities between photosynthesis and cellular respiration quizlet?

What are some similarities in photosynthesis and cellular respiration? They have the same reactions but accruing in reverse. In Photosynthesis, carbon dioxide and water is yielded to glucose and oxygen. In respiration, glucose and oxygen is yielded to carbon dioxide and water.

Can photosynthesis occur without cellular respiration?

Photosynthesis and cellular respiration are both part of a mutually beneficial relationship. Cellular respiration cannot occur without photosynthesis, and photosynthesis certainly cannot occur without the help of its partner.

Which enzyme is used both in photosynthesis and cellular respiration?

What enzyme is present in both photosynthesis and cellular respiration? An enzyme called ATP synthase uses that potential energy to synthesize a molecule called ATP, which is the most common energy currency for cells, and which is used in the dark reactions of photosynthesis.

When is photosynthesis introduced in the context of green plants?

They have also been introduced to photosynthesis in the context of green plants and food chains in Gr. 5 and 6. The emphasis in this chapter is on the use of energy and on how radiant (light) energy is transferred to chemical potential energy and later released during respiration.

What is the relationship between cellular respiration and photosynthesis?

The relationship between photosynthesis and cellular respiration is such that the products of one system are the reactants of the other. Photosynthesis involves the use of energy from sunlight, water and carbon dioxide to produce glucose and oxygen. Cellular respiration uses glucose and oxygen to produce carbon dioxide and water.

How are photosynthesis and respiration used to sustain life?

This is the never ending cycle that sustains life on earth. The process of photosynthesis is used by plants and other photosynthetic organisms to produce energy, whereas the process of cellular respiration breaks down the energy for use.

What kind of energy does photosynthesis use to produce oxygen?

Photosynthesis involves the use of energy from sunlight, water and carbon dioxide to produce glucose and oxygen. Cellular respiration uses glucose and oxygen to produce carbon dioxide and water.
