Does photosynthesis or cellular respiration use oxygen?

Does photosynthesis or cellular respiration use oxygen?

While photosynthesis requires carbon dioxide and releases oxygen, cellular respiration requires oxygen and releases carbon dioxide. It is the released oxygen that is used by us and most other organisms for cellular respiration.

Does cellular respiration break down oxygen?

During aerobic cellular respiration, glucose reacts with oxygen, forming ATP that can be used by the cell. Carbon dioxide and water are created as byproducts. In cellular respiration, glucose and oxygen react to form ATP….Aerobic vs anaerobic respiration.

	Aerobic	Anaerobic
Reactants	Glucose and oxygen	Glucose

Does photosynthesis break down oxygen?

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.

What’s the role of oxygen in cellular respiration?

Oxygen plays a vital role in energy production via a system called electron transport chain (ETC), which is an important component of cellular respiration. Oxygen acts as a final electron acceptor that helps move electrons down a chain that results in adenosine triphosphate production.

How do photosynthesis and cellular respiration differ?

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.

How does cellular respiration use oxygen?

How is oxygen used in cellular respiration? Oxygen is used as the end electron acceptor for the electron transport chain in cellular respiration. It allows electrons to be transferred through the electron transport chain in order to create an electrochemical gradient for hydrogen to create ATP.

What role does oxygen play in photosynthesis and cellular respiration?

What roles does oxygen play in photosynthesis and in cellular respiration? Photosynthesis releases oxygen into the atmosphere as a. product, whereas cellular respiration uses oxygen as a reactant to release energy from food.

How does photosynthesis and cellular respiration work together?

Photosynthesis converts carbon dioxide and water into oxygen and glucose. 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 the role of oxygen in photosynthesis and cellular respiration?

While water is broken down to form oxygen during photosynthesis, in cellular respiration oxygen is combined with hydrogen to form water. While photosynthesis requires carbon dioxide and releases oxygen, cellular respiration requires oxygen and releases carbon dioxide. Without oxygen, much less ATP would be produced.

What does oxygen do in photosynthesis?

Oxygen (O2) is evolved during photosynthetic electron transport when water is split by the oxygen-evolving complex to provide protons and electrons to the chloroplastic electron chain, thereby generating ATP and NADPH—the energy source and reducing power for plant metabolism.

What type of cellular respiration requires oxygen?

Aerobic respiration
Aerobic respiration is a specific type of cellular respiration, in which oxygen (O2) is required to create ATP.

How are molecules broken down during cellular respiration?

After the large molecules in food are broken down into their smaller subunits during digestion, the small molecules can be further broken down to transfer their energy to ATP. During cellular respiration, enzymes slowly rearrange the atoms in food molecules.

Why is it important to know about cellular respiration?

Respiration, which is more commonly referred to as breathing, is the physical act of inhaling and exhaling. Cellular respiration is what happens inside cells when they use oxygen to transfer energy from food to ATP. Cellular respiration is essential to the transfer of matter and energy through living systems.

How does cellular respiration transfer energy to ATP?

The third pathway, oxidative phosphorylation, transfers the energy from the food molecules to ATP. Here are the basics of how cellular respiration works: During glycolysis, which occurs in the cytoplasm of the cell, cells break glucose down into pyruvate, a three-carbon compound.

How does cellular respiration work in the mitochondrion?

Here are the basics of how cellular respiration works: During glycolysis, which occurs in the cytoplasm of the cell, cells break glucose down into pyruvate, a three-carbon compound. After pyruvate is converted to acetyl-coA, cells use the Krebs cycle (which occurs in the matrix of the mitochondrion) to break down acetyl-coA into carbon dioxide.
