What is carbon dioxide in cellular respiration?

What is carbon dioxide in cellular respiration?

During the process of cellular respiration, carbon dioxide is given off as a waste product. This carbon dioxide can be used by photosynthesizing cells to form new carbohydrates. Also in the process of cellular respiration, oxygen gas is required to serve as an acceptor of electrons.

Why is carbon dioxide a reactant in photosynthesis?

The equation shows that the “ingredients” for photosynthesis are carbon dioxide, water, and light energy. Plants, algae, and photosynthetic bacteria take in light from the sun, molecules of carbon dioxide from the air, and water molecules from their environment and combine these reactants to produce food (glucose).

Is carbon dioxide a product or reactant in photosynthesis?

In photosynthesis, oxygen, carbon dioxide, ATP, and NADPH are reactants. GA3P and water are products. In photosynthesis, chlorophyll, water, and carbon dioxide are reactants.

What are the reactants for cellular respiration?

Carbon dioxide + Water Glucose (sugar) + Oxygen CO2 + H2O C6H12O6 + 6O2 Cellular respiration or aerobic respiration is a series of chemical reactions which begin with the reactants of sugar in the presence of oxygen to produce carbon dioxide and water as waste products.

What are the three main stages of aerobic cellular respiration?

Aerobic respiration is divided into three main stages: Glycolysis, Citric acid cycle and Electron transport chain. Glycolysis: Glucose ( 6 carbon atoms) is split into 2 molecules of glyceraldehyde phosphate (3 carbon each), then these are turned into pyruvate (3 carbons each).

What stage of cellular respiration gives off carbon dioxide?

glycolysis

Where is co2 released in aerobic respiration?

Thus three times carbon dioxide is released during the course of aerobic respiration- once during oxidative decarboxylation of pyruvate and two during the Krebs or citric acid cycle.

What are 2 differences between aerobic and anaerobic respiration?

Aerobic respiration takes place in the mitochondria and requires oxygen and glucose, and produces carbon dioxide, water, and energy. Anaerobic respiration also produces energy and uses glucose, but it produces less energy and does not require oxygen.

What are the end products of respiration in yeast?

Yeast undergoes fermentation, a type of anaerobic respiration, which takes place in the absence of oxygen. The end products are carbon dioxide, alcohol and energy.

What are the end product of anaerobic respiration in muscles?

The end products of anaerobic respiration are Lactic acid or ethanol and ATP molecules. Anaerobic respiration takes place in the absence of oxygen and is seen in lower animals.

What is difference between aerobic and anaerobic respiration Class 7?

Differences: Aerobic respiration takes place in presence of oxygen; whereas anaerobic respiration takes place in absence of oxygen. Carbon dioxide and water are the end products of aerobic respiration, while alcohol is the end product of anaerobic respiration.

What is aerobic respiration Class 7?

When the breakdown of glucose food occurs with the use of oxygen, it is called aerobic respiration. In aerobic respiration, the glucose food is completely broken down into carbon dioxide and water with the use of oxygen, and energy is released.

What are three differences between anaerobic and aerobic respiration?

Anaerobic respiration is a process of cellular respiration in which the excessive energy electron acceptor is neither oxygen nor pyruvate derivatives….

Aerobic Respiration Anaerobic Respiration
Glucose breaks down into carbon dioxide and water. Glucose breaks down into ethyl alcohol, carbon dioxide, and energy.

Is glycolysis aerobic or anaerobic?

Glycolysis, as we have just described it, is an anaerobic process. None of its nine steps involve the use of oxygen. However, immediately upon finishing glycolysis, the cell must continue respiration in either an aerobic or anaerobic direction; this choice is made based on the circumstances of the particular cell.

What are anaerobes give example?

Examples. Examples of obligately anaerobic bacterial genera include Actinomyces, Bacteroides, Clostridium, Fusobacterium, Peptostreptococcus, Porphyromonas, Prevotella, Propionibacterium, and Veillonella.
