Where do each of the stages of cellular respiration occur?
Where do each of the stages of cellular respiration occur?
Stages of Cellular Respiration Glycolysis occurs in the cytosol of the cell and does not require oxygen, whereas the Krebs cycle and electron transport occur in the mitochondria and do require oxygen.
Where does cellular respiration occur in the cell?
mitochondria
Where does respiration and cellular respiration occur?
Mitochondria
What is the relationship between cellular respiration and breathing?
Cellular respiration is not the same thing as breathing, but they are closely related. When you breathe in, you take in the When you breathe in, you take in the oxygen your cells need for cellular respiration. When you breathe out, you get rid of the carbon dioxide that your cells produce during cellular respiration.
What is the difference between the two types of cellular respiration?
There are two types of cellular respiration, aerobic and anaerobic. Aerobic respiration is more efficient and can be utilized in the presence of oxygen, while anaerobic respiration does not require oxygen.
What is true about both photosynthesis and cellular respiration choose the two correct answers?
Explanation: Both photosynthesis and cellular respiration are chemical processes. Both processes involves the use of energy. Photosynthesis requires energy from the sun and cellular respiration requires energy rich molecules such as ATP.
Where does oxygen end up in cellular respiration?
In the presence of oxygen, under aerobic conditions, pyruvate enters the mitochondria to proceed into the Krebs cycle. The second stage of cellular respiration is the transfer of the energy in pyruvate, which is the energy initially in glucose, into two energy carriers, NADH and FADH2.
What do you think will happen if cellular respiration is disrupted?
Answer: If cellular respiration stops, a cell dies because if cellular respiration ceases, the cell will switch to using pyruvate or a pyruvate-derived…
What is the first step of cellular respiration?
Glycolysis is the first pathway in cellular respiration. This pathway is anaerobic and takes place in the cytoplasm of the cell. This pathway breaks down 1 glucose molecule and produces 2 pyruvate molecules. There are two halves of glycolysis, with five steps in each half.
Is the first step in cellular respiration that begins releasing energy?
glycolysis
What is cellular respiration and why is it so important to life on earth what would happen if there was no cellular respiration?
Cellular respiration is essentially the counterpart to photosynthesis, which uses sunlight as an energy source and provides Earth with oxygen. Without photosynthesis in plants, we would not have the oxygen needed for cellular respiration and could not provide our cells with the energy, or ATP, they need to live.
Why are photosynthesis and cellular respiration not opposite processes?
Photosynthesis and cellular respiration are almost opposite because photosynthesis takes in CO2 and releases oxygen whereas cellular respiration takes in oxygen and releases CO2.
What happens if there is not enough oxygen for cellular respiration?
When oxygen is not present and cellular respiration cannot take place, a special anaerobic respiration called fermentation occurs. Fermentation starts with glycolysis to capture some of the energy stored in glucose into ATP.
What are the main steps of cellular respiration in the presence of oxygen?
The stages of cellular respiration include glycolysis, pyruvate oxidation, the citric acid or Krebs cycle, and oxidative phosphorylation.
