Does cellular respiration use oxygen?

User Avatar

Asked by Wiki User

C6H12O6 + 6O2 + 6H2O -----> 6CO2 + 12H2O + energy

Easier:

glucose (sugar) molecules + oxygen molecules = carbon dioxide molecules, water molcules, and energy

**Oxygen is used to create energy in cellular respiration**

(CO2 and H2O are waste products)

What is the function of Atp in Cellular respiration?

User Avatar

Asked by Wiki User

ATP (adenosine triphosphate) is the primary energy carrier molecule in cellular respiration. It is produced through the process of oxidative phosphorylation and is used by cells to power various cellular activities and processes, such as muscle contraction, protein synthesis, and active transport. ATP acts as a temporary energy source that can be quickly broken down to release energy for cellular functions.

Classify photosynthesis and cellular respiration according to the metabolism?

User Avatar

Asked by Wiki User

Photosynthesis is an anabolic process as it builds complex organic molecules (like glucose) using energy from sunlight, converting carbon dioxide and water into carbohydrates. Cellular respiration is a catabolic process, breaking down complex organic molecules (like glucose) to release energy in the form of ATP, which cells can use for various functions.

How does cellular respiration depend on photosynthesis?

User Avatar

Asked by Wiki User

Cellular respiration relies on photosynthesis for the production of glucose, which serves as the primary energy source. Through photosynthesis, plants convert sunlight, CO2, and water into glucose and oxygen. During cellular respiration, glucose is broken down to release energy in the form of ATP, which is necessary for cellular functions.

Where does the produced pyruvate go in the second stage of cellular respiration?

User Avatar

Asked by Wiki User

In the second stage of cellular respiration, pyruvate is transported into the mitochondria, where it enters the citric acid cycle (also known as the Krebs cycle). Within the citric acid cycle, pyruvate is further broken down to generate energy in the form of ATP.

How is respiration useful?

User Avatar

Asked by Wiki User

Respiration is essential for living organisms as it is the process through which cells generate energy by converting glucose and oxygen into ATP, which is the energy currency of the cell. It also helps in releasing carbon dioxide, a waste product, from the body.

Compare and contrast the terms photosynthesis and cellular respiration?

User Avatar

Asked by Wiki User

Photosynthesis is the process by which plants, algae, and some bacteria convert sunlight, carbon dioxide, and water into glucose and oxygen. Cellular respiration is the process by which cells break down glucose to release energy, which is used to power cellular activities. While photosynthesis produces oxygen and glucose, cellular respiration consumes oxygen and glucose to produce energy, carbon dioxide, and water. Both processes are essential for the survival of living organisms.

How do deforestation fire and combustion of fossil fuels disrupt the balance between photosynthesis and cellular respiration?

User Avatar

Asked by Wiki User

Deforestation and combustion of fossil fuels release excess carbon dioxide into the atmosphere. This disruption upsets the natural balance between photosynthesis, which utilizes carbon dioxide, and cellular respiration, which releases carbon dioxide. The increase in carbon dioxide levels leads to climate change and impacts the Earth's temperature and weather patterns.

What is the role of the electron transport chain in cellular respiration?

User Avatar

Asked by Wiki User

The electron transport chain is responsible for transferring electrons from NADH and FADH2 to oxygen, generating ATP in the process. This ATP production is the final step in cellular respiration and provides the energy needed for various cellular activities.

How is cellular respiration and photosynthesis similar?

User Avatar

Asked by Wiki User

Cellular respiration and photosynthesis are both fundamental processes for living organisms. Both involve the transformation of energy, with cellular respiration breaking down glucose to release energy and photosynthesis using sunlight to produce glucose. Additionally, both processes involve the exchange of gases, with cellular respiration releasing carbon dioxide and photosynthesis utilizing it to produce oxygen.

Can cellular respiration be described as the conversion of the energy?

User Avatar

Asked by Wiki User

Yes, cellular respiration is the process in which cells break down glucose and other organic molecules to produce ATP, which is the cell's primary energy source. This conversion process occurs in multiple stages, including glycolysis, the citric acid cycle, and oxidative phosphorylation, which collectively generate ATP for cellular functions.

What liberates the most energy in the form of ATP?

User Avatar

Asked by Wiki User

Aerobic respiration liberates the most energy in the form of ATP compared to other cellular processes like anaerobic respiration and fermentation.

How go photosynthesis and respiration work together in the biosphere?

User Avatar

Asked by Wiki User

Photosynthesis and respiration are interconnected processes in the biosphere. During photosynthesis, plants use sunlight to convert carbon dioxide and water into glucose and oxygen, while respiration involves the breakdown of glucose to produce energy, carbon dioxide, and water. These processes are complementary, as photosynthesis releases oxygen that is used in respiration, and respiration releases carbon dioxide that is used in photosynthesis. Together, they play a critical role in the cycling of carbon and oxygen in the biosphere.

What is equation for respiration an photosynthesis?

User Avatar

Asked by Wiki User

You probably mean the chemical equation for plant respiration. There are two kinds of respiration, so there are two different equations. 1) Aerobic respiration is respiration which uses oxygen: glucose + oxygen = water + carbon dioxide + ENERGY C6H12O6 + 6O2 = 6H2O + 6CO2 + ENERGY Aerobic respiration is the same in animals and plants. 2) Anaerobic respiration is respiration without using oxygen. This is different in plants and animals. In plants: glucose = carbon dioxide + ethanol (alcohol) + ENERGY C6H12O6 = 2CO2 + 2C2H5OH + ENERGY In animals: glucose = lactic acid + ENERGY C6H12O6 = 2C3H6O3 + ENERGY See: http://en.wikipedia.org/wiki/Anaerobic_respiration http://en.wikipedia.org/wiki/Fermentation_%28biochemistry%29

List the products of glycolysis what is the role of each of these products in cellular respiration?

User Avatar

Asked by Wiki User

The products of glycolysis are 2 molecules of ATP, 2 molecules of NADH, and 2 molecules of pyruvate. ATP provides energy for cellular functions, NADH transfers electrons to the electron transport chain for ATP production, and pyruvate enters the citric acid cycle to generate more ATP through oxidative phosphorylation.

Asked by Wiki User

Cellular respiration occurs in the mitochondria of eukaryotic cells. It is the process by which cells break down glucose molecules to produce energy in the form of ATP. Oxygen is required for this process to efficiently convert the energy stored in glucose into ATP.

What are products of cellular respiration?

User Avatar

Asked by Wiki User

The products of cellular respiration include ATP (energy), carbon dioxide, and water. These products are generated through a series of metabolic reactions that break down glucose to release energy for the cell to use.

Gas released in respiration?

User Avatar

Asked by Wiki User

During respiration, carbon dioxide gas is released as a byproduct of cellular metabolism. This occurs during the process of breaking down glucose to produce energy in the form of ATP. Carbon dioxide is then exhaled out of the body through the lungs when we breathe.

User Avatar

Asked by Wiki User

The products of photosynthesis that begin cellular respiration are glucose and oxygen. Glucose is broken down in the process of cellular respiration to release energy, and oxygen is used as the final electron acceptor in the electron transport chain to produce ATP.

How are cellular respiration and photosynthesis complementary processes?

User Avatar

Asked by Wiki User

Cellular respiration and photosynthesis are complementary processes because they have opposite reactions. Photosynthesis uses light energy to convert carbon dioxide and water into glucose and oxygen, while cellular respiration uses glucose and oxygen to produce ATP, releasing carbon dioxide and water as byproducts. Essentially, the products of one process are used as reactants for the other process, creating a cycle that sustains life on Earth.
