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 major chemical reactions of cellular respiration?

The stages of cellular respiration include glycolysis, pyruvate oxidation, the citric acid or Krebs cycle, and oxidative phosphorylation.

What is the chemical reaction for cellular respiration quizlet?

Cellular respiration is represented by the chemical formula C6H12 + 6O2 = 6CO2 + 6H2O + energy (as ATP).

What type of chemical reaction is cellular respiration?

The reactions of cellular respiration are catabolic reactions. In catabolic reactions, bonds are broken in larger molecules and energy is released. In cellular respiration, bonds are broken in glucose, and this releases the chemical energy that was stored in the glucose bonds.

What are the 3 stages of cellular respiration?

Summary: the three stages of Aerobic Respiration Carbohydrates are broken down using all three stages of respiration (glycolysis, citric acid cycle and the electron transport chain).

Is cellular respiration A chemical reaction Why?

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 is the chemical equation for cellular respiration in words?

C 6 H 12 O 6 + 6 O 2 –> 6 CO 2 + 6 H 2 O + ATP is the complete balanced chemical formula for cellular respiration.

What is the general chemical equation of cellular respiration label the reactants and the products?

C6H12O6 + O2 ——> CO2 + H2O + ATP. The reactants are oxygen and glucose. The products are ATP, CO2, and water.

What is the chemical equation for cellular respiration of glucose?

The equation for cellular respiration is: C6H12O6 + 6O2 → 6CO2 + 6H20 + energy (Glucose + Oxygen yields Carbon Dioxide + Water + Energy) You may notice that the equation for cellular respiration is the opposite of the equation for photosynthesis.

What is the chemical equation for glycolysis and respiration?

The net equation for glycolysis is as follows: C6H12O6 + 2 ADP + 2 [P]i + 2 NAD+ –> 2 pyruvate + 2 ATP + 2 NADH, where C6H12O6 is glucose, [P]i is a phosphate group, NAD+ and NADH are electron acceptors/carriers and ADP is adenosine diphosphate.

What are the 4 stages of respiration?

There are four stages: glycolysis, the link reaction, the Krebs cycle and oxidative phosphorylation.

What are the 3 main steps in the electron transport chain?

• Generation of a proton gradient across the mitochondrial membrane. Proton accumulation occurs in the intermembrane space of mitochondria.
• Reduction of molecular oxygen and formation of water. …
• ATP synthesis by chemiosmosis.

Where do most reactions of respiration occur?

Most aerobic respiration happens in the mitochondria, but anaerobic respiration takes place in the fluid portion of the cytoplasm.

In what ways are the chemical reactions of photosynthesis and cellular respiration similar?

Photosynthesis and cellular respiration are similar because both reactions contain water, carbon dioxide, glucose, oxygen and energy.

How are chemical reactions important in cells?

Chemical Reactions that Make Energy Chemical reactions are crucial for our cells to make energy, or ATP. All living things need energy to survive and ATP is actually a reactant that drives many other chemical reactions inside cells. Cells use a process called cellular respiration to make energy.

What type of reaction is cellular respiration Exergonic or Endergonic?

Photosynthesis is an endergonic (energy-consuming) process. Cellular respiration is an exergonic (energy-releasing) process.

Which equation shows a chemical reaction that occurs during anaerobic cell respiration?

Some examples of anaerobic respiration include alcohol fermentation, lactic acid fermentation and in decomposition of organic matter. The equation is: glucose + enzymes = carbon dioxide + ethanol / lactic acid.

What are the products of cellular respiration?

In cellular respiration, glucose and oxygen react to form ATP. Water and carbon dioxide are released as byproducts. The three stages of aerobic cellular respiration are glycolysis (an anaerobic process), the Krebs cycle, and oxidative phosphorylation.

Which equation summarizes the process of respiration *?

Cellular respiration involves many biochemical reactions. However, the overall process can be summed up in a single chemical equation: C6H12O6 + 6O2 → 6CO2 + 6H2O + energy (stored in ATP) Cellular respiration uses oxygen in addition to glucose.

What happens during cellular respiration?

cellular respiration, the process by which organisms combine oxygen with foodstuff molecules, diverting the chemical energy in these substances into life-sustaining activities and discarding, as waste products, carbon dioxide and water.

In which reactions of cellular respiration does oxidative phosphorylation occur?

Oxidative phosphorylation occurs in the mitochondria, and the two reactions (oxidation of NADH or FADH2 and phosphorylation to generate ATP) are coupled by a proton gradient across the inner membrane of the mitochondria (Figure 9).

What is the final electron acceptor in cellular respiration?

Oxygen is the final electron acceptor in this respiratory cascade, and its reduction to water is used as a vehicle by which to clear the mitochondrial chain of low-energy, spent electrons.

What is complex 4 in the electron transport chain?

Complex IV of the electron transport chain, also known as cytochrome c oxidase, is a multiunit structure that functions to transfer electrons form cytochrome c to oxygen and in the process form water and help generate a proton gradient. … CuB associates with heme A-3 to help reduce oxygen into water.

Where does cellular respiration occur?

While most aerobic respiration (with oxygen) takes place in the cell’s mitochondria, and anaerobic respiration (without oxygen) takes place within the cell’s cytoplasm.

What are the two types of cellular respiration?

There are two types of cellular respiration (see Cellular Respiration concept): aerobic and anaerobic. One occurs in the presence of oxygen (aerobic), and one occurs in the absence of oxygen (anaerobic). Both begin with glycolysis – the splitting of glucose.

What is the chemical reaction of photosynthesis?

The process of photosynthesis is commonly written as: 6CO2 + 6H2O → C6H12O6 + 6O2. This means that the reactants, six carbon dioxide molecules and six water molecules, are converted by light energy captured by chlorophyll (implied by the arrow) into a sugar molecule and six oxygen molecules, the products.
