What else can I help you with?
This is the process that releases energy by breaking down food molecules in the presence of oxygen.?
The glycolysis and the Krebs cycle uses the oxygen to break down the food molecules in order to release energy.
What happens to energy During cellular respiration?
Energy is burned or is used up during this process. During cellular respiration, molecules of glucose are broken down in order to convert the stored energy into a usable form of energy.
What is cellular respiration performed by?
Cellular respiration is performed by the mitochondria of a cell. It involves a series of complex biochemical reactions that convert glucose and oxygen into energy in the form of ATP (adenosine triphosphate) for the cell to use.
Respiration releases what amount of energy Large or small?
Effective cellular respiration releases a large amount of energy (ATP). In order for effective cellular respiration to occur, oxygen must be present in the second stage of cellular respiration, the Krebs Cycle. If after the first stage of cellular respiration, glycolysis, there is no oxygen present, then ineffective cellular respiration occurs and the process is carried out by fermentation. Fermentation is an anaerobic process that results in the formation of ethyl alcohol or lactic acid and the cycle produces a net ATP gain of 2, whereas the net ATP gain of effective cellular respiration is 36 ATP molecules. Therefore cellular respiration in the presence of oxygen deals out a large amount of energy, but if not in the presence of oxygen, it deals out a small amount of energy.
Do Plants perform cellular respiration?
Yes, plants perform cellular respiration to generate energy by breaking down glucose molecules in the presence of oxygen. This process occurs in plant cells' mitochondria, releasing carbon dioxide, water, and ATP as byproducts.
Why do the cells of all living things carry out cellular respiration continuously?
Living things use energy in order to live, so we are constantly using converting ATP to ADP in order to get that energy. Cellular respiration replenishes the ATP by converting ADP back into ATP, which living things use for energy. Without cellular respiration an organism would die from lack of ATP, and therefore a lack of energy.
Cellular respiration does what to glucose?
Cellular respiration breaks down glucose in order to make energy (ATP).
What three things must be present in order for respiration to occur?
In order for respiration to occur, three things must be present: oxygen, a source of energy (such as glucose), and a metabolic system capable of breaking down the energy source to release energy for cellular processes.
Why is cellular respiration so important to all living things?
Cellular respiration is the process that produces usable cellular energy in the form of ATP. The organisms that run cellular respiration rely on it because their cells need the energy in order to function and live.
What does cellular respiration break down in order to release energy?
glucose is broken down in glycolysis during respiration to release energy
What does all living things including pants must do in order to obtain energy?
All living things, including plants, obtain energy through the process of photosynthesis or cellular respiration. Photosynthesis is the process by which plants convert sunlight into energy, while cellular respiration is the process by which organisms extract energy from food molecules. Both processes are essential for all living things to survive and function.
This is the process that releases energy by breaking down food molecules in the presence of oxygen.?
The glycolysis and the Krebs cycle uses the oxygen to break down the food molecules in order to release energy.
Does cellular respiration happen in humans?
Yes, cellular respiration occurs in humans. Life depends on this process in order to create enough energy to run all cellular activites that allow us to function.
What is the relationship of calories to cellular respiration?
Calories are a form of energy. Any time a cell converts food into energy then the cell is breathing. So the relationship is that in order for cell respiration to occur the cell must convert food and calories (energy).
What happens to energy During cellular respiration?
Energy is burned or is used up during this process. During cellular respiration, molecules of glucose are broken down in order to convert the stored energy into a usable form of energy.
Product of cellular respiration?
Cellular respiration is the process by which the chemical energy of "food" molecules is released and partially captured in the form of ATP. Carbohydrates, fats, and proteins can all be used as fuels in cellular respiration, but glucose is most commonly used as an example to examine the reactions and pathways involved.
Does cellular respiration release glucose?
Yes - glucose is broken down in the first step of cellular respiration. This stage is known as glycolysis and occurs in the cytoplasm. Cellular respiration begins with glucose and ends creating ATP.
