What is the role of carbon dioxide in photosynthesis and in cellular respiration?

What is the role of carbon dioxide in photosynthesis and in cellular respiration?

Photosynthesis makes the glucose that is used in cellular respiration to make ATP. 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.

What role does carbon dioxide play 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.

What steps of cellular respiration generate carbon dioxide?

During the process of glycolysis in cellular respiration, glucose is oxidized to carbon dioxide and water. Energy released during the reaction is captured by the energy-carrying molecule ATP (adenosine triphosphate).

What happens to carbon dioxide and water after cellular respiration?

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. Water and carbon dioxide are released as byproducts.

Where does the carbon dioxide go in cellular respiration?

The products of cellular respiration are carbon dioxide and water. Carbon dioxide is transported from your mitochondria out of your cell, to your red blood cells, and back to your lungs to be exhaled. ATP is generated in the process.

What is the main source of energy for cellular respiration?

glucose

What is the oxygen used for and where does the carbon dioxide come from?

Trees and plants give off carbon dioxide when they breathe, and when they die and rot. We breathe in oxygen and some of this carbon dioxide. When we exhale, we breathe out less oxygen but more carbon dioxide than we inhale. The carbon we breathe out as carbon dioxide comes from the carbon in the food we eat.

What is the correct order for the three steps of aerobic respiration?

Aerobic respiration is divided into three main stages: Glycolysis, Citric acid cycle and Electron transport chain.

What is the process of aerobic respiration?

Aerobic respiration is the process of producing cellular energy involving oxygen. Cells break down food in the mitochondria in a long, multistep process that produces roughly 36 ATP. Aerobic respiration is the process of breaking down the food that comes into a cell using oxygen to help power that process.

What is the correct order of respiration?

Ch. 9 Honors Biology Cellular Respiration

Question	Answer
What is the correct sequence of stages of cellular respiration?	glycolysis, Krebs Cycle, Electron Transport Chain
What is the correct equation for cellular respiration?	C6H12O6 + 6 O2 –> 6 CO2 + 6 H2O
What are the products of cellular respiration?	CO2, H2O, ATP

What are the three stages of aerobic cellular respiration in the correct order from 1 to 3?

Answer: The correct answer is- 1) Glycolysis, 2) Kreb cycle, 3) Electron transport chain. Cellular respiration is a process of oxidation of food molecule ( like glucose) so as to form carbon dioxide, water, and large amount of energy in the form of ATP ( adenosine triphosphate).

What process does not require oxygen?

Metabolic processes that require oxygen are called aerobic. Metabolic processes that do not require oxygen are called anaerobic.

What are the four stages of aerobic respiration?

Aerobic respiration involves four stages:

• glycolysis,
• a transition reaction that forms acetyl coenzyme A,
• the citric acid (Krebs) cycle, and an electron transport chain and.
• chemiosmosis.

What are the 3 main parts of cellular respiration?

Cellular respiration is a collection of three unique metabolic pathways: glycolysis, the citric acid cycle, and the electron transport chain.

What is the cellular respiration formula?

Notice that the equation for cellular respiration is the direct opposite of photosynthesis: Cellular Respiration: C6H12O6 + 6O2 → 6CO2 + 6H2O.

What is the relationship between photosynthesis and cellular 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 are the two main parts of cellular respiration?

What two ways foes cellular respiration occur in? It occurs in two main stages: krebs cycle (stage 1) and electron transport (stage 2).

What is it called when cellular respiration occurs in the absence of oxygen?

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

What are the two stages of aerobic respiration?

Aerobic (“oxygen-using”) respiration occurs in three stages: glycolysis, the Krebs cycle, and electron transport. In glycolysis, glucose is split into two molecules of pyruvate. This results in a net gain of two ATP molecules. Life first evolved in the absence of oxygen, and glycolysis does not require oxygen.

What are the steps of respiration?

Cellular respiration takes in food and uses it to create ATP, a chemical which the cell uses for energy. Usually, this process uses oxygen, and is called aerobic respiration. It has four stages known as glycolysis, Link reaction, the Krebs cycle, and the electron transport chain.

What are the 5 processes of respiration?

Terms in this set (5)

• Pulmonary Ventilation. Movement of air in and out of the lungs passage (Thorax and Diaphragm).
• External Respiration. Exchange of gases between air and blood at pulmonary capillaries (Alveoli).
• Transport of gases through blood vessels.
• Internal Respiration.
• Cellular Respiration.

What is the first step in respiration?

The first stage of cellular respiration, called glycolysis, takes place in the cytoplasm. In this step, enzymes split a molecule of glucose into two molecules of pyruvate. The energy released from these reactions produces 2 molecules of ATP and 2 molecules of NADH.

What are the 5 main respiration events?

Terms in this set (5)

• pulmonary ventilation. O2 into lungs from inspired air; CO2 out of lungs from expired air.
• external respiration. gas exchange between alveoli and the capillaries.
• respiratory gas transport. gasses are transported in blood (via vessels) to tissues.
• internal respiration.
• cellular respiration.

What are the 10 organs of the respiratory system?

These are the parts:

• Nose.
• Mouth.
• Throat (pharynx)
• Voice box (larynx)
• Windpipe (trachea)
• Large airways (bronchi)
• Small airways (bronchioles)
• Lungs.

What are the events in respiration?

Four Events of Respiration

• Pulmonary Ventilation. (Breathing) Process of moving air into and out of the lungs to change and refresh gas in the lungs.
• External Respiration. Process of exchanging gas (O2 and CO2) between blood and alveoli.
• Respiratory Gas Transport.
• Internal Respiration.

What are the events in human respiration?

Respiration is the sequence of events that results in the exchange of oxygen and carbon dioxide between the atmosphere and the body cells. Every 3 to 5 seconds, nerve impulses stimulate the breathing process, or ventilation, which moves air through a series of passages into and out of the lungs.
