- Carbon dioxide is absorbed by plants during photosynthesis, where it is converted into oxygen and glucose.
- Oxygen is released by plants as a byproduct of photosynthesis and is used by animals during respiration.
- Animals inhale oxygen and exhale carbon dioxide as a waste product of respiration.
- Carbon dioxide is absorbed by plants again to continue the cycle.
- This constant exchange of gases between plants and animals helps maintain the balance of oxygen and carbon dioxide in the atmosphere.

What generates most of the carbon dioxide produced by cellular respiration?
During cellular respiration, the majority of carbon dioxide is produced as a byproduct from the breakdown of glucose during the citric acid cycle (also known as the Krebs cycle) and the subsequent steps in the mitochondria. The carbon dioxide is then released as waste through exhalation.
What are the 8 steps in the oxygen and carbon dioxide exchange?
Inhalation: Breathing in air containing oxygen. Alveolar gas exchange: Oxygen diffuses from the alveoli into the bloodstream, while carbon dioxide moves in the opposite direction. Transportation: Oxygen binds to hemoglobin in red blood cells for delivery to tissues, while carbon dioxide is carried back to the lungs. Cellular respiration: Oxygen is used by cells for energy production, while carbon dioxide is produced as a byproduct. Carbon dioxide transport: Carbon dioxide is transported in the blood in three forms: dissolved in plasma, bound to hemoglobin, or as bicarbonate ions. Tissue gas exchange: Oxygen diffuses from the blood into tissues, while carbon dioxide moves from tissues into the blood. Cellular metabolism: Oxygen is used in the mitochondria to produce ATP through aerobic respiration, while carbon dioxide is produced as a waste product. Exhalation: Removing carbon dioxide from the body by breathing it out.
Which part of the photosynthetic process requires ATP NADPH and carbon dioxide to produce glucose?
The Calvin cycle
What is the process by which the breakdown of glucose is completed and CO2 is produced?
The breakdown of glucose into carbon dioxide and water is known as cellular respiration. This process occurs in multiple steps, including glycolysis, the Krebs cycle, and oxidative phosphorylation. During these steps, glucose is gradually broken down to release energy in the form of ATP, with carbon dioxide being produced as a byproduct.
What are the two basic steps to photosynthesis?
The Light Dependent process and then the Light Independent process (known as the Calvin Cycle).
What are the steps in oxygen cycle?
The oxygen cycle involves several key steps: 1) Photosynthesis by plants and phytoplankton, where they use sunlight to convert carbon dioxide into oxygen, 2) Animals then breathe in oxygen and use it for respiration, converting it back into carbon dioxide, 3) Decomposers break down dead organic matter and release carbon dioxide, completing the cycle.
What are the steps for external respiration?
External respiration involves the exchange of oxygen and carbon dioxide between the lungs and blood. The steps include: 1. Inhalation: Oxygen is taken in through the airways into the lungs. 2. Oxygen exchange: Oxygen diffuses from the lungs into the bloodstream, while carbon dioxide moves from the blood into the lungs. 3. Exhalation: Carbon dioxide is expelled from the lungs when we breathe out.
Which of the following steps represents a correct source of carbon dioxide during aerobic respiration?
Citric acid cycle
Which of the following does not occur during the Calvin cycle?
The consumption of oxygen does not occur during the Calvin cycle. This process involves carbon fixation, reduction of carbon compounds, and regeneration of RuBP. Oxygen is not directly involved in these steps.
In anaerobic respiration what steps produce carbon dioxide?
It's called the Krebs's cycle and it consists of the steps to convert a 2 carbon sugar into CO2 and H2O. (And you don't own the genetic code to do this ... only the mitochondria do.)
What generates most of the carbon dioxide produced by cellular respiration?
During cellular respiration, the majority of carbon dioxide is produced as a byproduct from the breakdown of glucose during the citric acid cycle (also known as the Krebs cycle) and the subsequent steps in the mitochondria. The carbon dioxide is then released as waste through exhalation.
What is the four steps in photosynthesis?
The four steps in photosynthesis are light absorption by chlorophyll, water splitting to release oxygen, production of ATP and NADPH in the light-dependent reactions, and conversion of carbon dioxide into glucose in the Calvin cycle.
What is the steps for oxygen to become carbon dioxide?
During respiration, oxygen is inhaled into the lungs and diffuses into the bloodstream. It is then transported by red blood cells to cells in the body where it participates in cellular respiration, combining with nutrients to produce energy, carbon dioxide, and water. The carbon dioxide is then carried back to the lungs through the bloodstream where it is exhaled out of the body.
Where do the human lungs get the carbon dioxide to replace oxygen?
The human lungs get carbon dioxide from the bloodstream. As blood flows from the body's tissues to the lungs, it carries carbon dioxide. In the lungs, carbon dioxide is exchanged for oxygen during the process of respiration.
What are the 8 steps in the oxygen and carbon dioxide exchange?

What are converted into glucose and oxygen in the process of photosynthesis?
Carbon dioxide and water react during a series of steps to produce glucose and oxygen in the process of photosynthesis. The overall chemical reaction is:6CO2 + 6H2O ---> C6H12O6 + 6O2
Six carbons enter the second stage of aerobic respiration how many depart during the preparation steps and the cycle proper?
During the preparation steps in the second stage of aerobic respiration (Krebs cycle), two carbons depart as carbon dioxide in the conversion of pyruvate to acetyl-CoA. In the cycle proper, all six carbons that entered are released as carbon dioxide molecules in the form of three molecules of CO2.
