What degree do the physicists at Tufts have?
They have a Master's Degree in Cellular and Molecular Physiology from Tufts Medical School and a Master's of Teaching from Simmons College. They also are certified in secondary special education, biology, and physics in Massachusetts. This lesson focuses on oxygen in cellular respiration.
How to bring oxygen into the body?
Take a deep breath in and gently exhale. Every day, all day and all night, our lungs inhale and exhale air. Although calming, the goal of this process is to bring oxygen into the body.
Where does cellular respiration occur?
Glycolysis is the first step in cellular respiration, and it occurs in the main compartment of the cell: the cytoplasm. Cells let glucose in from the blood--the glucose comes from the food we eat. Next, cells convert glucose through several different compounds to make two ATP molecules and a molecule called pyruvate. A compound called NADH (nicotinamide adenine dinucleotide + hydrogen) is also created. This molecule stores electrons harvested from the glucose, which will be used later to create a larger amount of ATP.
Who is Amanda Robb?
Amanda has taught high school science for over 10 years. They have a Master's Degree in Cellular and Molecular Physiology from Tufts Medical School and a Master's of Teaching from Simmons College. They also are certified in secondary special education, biology, and physics in Massachusetts.
Do cells need oxygen?
Our body cells need oxygen to do this process, although other organisms, like yeast or bacteria, don't always need it. They have other ways of making energy. But since the focus of this particular lesson is on the role of oxygen, we'll stick with animal cells, like the ones in our body.
What do cells use to make energy?
All body cells engage in cellular respiration. They use oxygen and glucose, a sugar found in the foods we eat and convert them to ATP (adenosine triphosphate), or cellular energy, and carbon dioxide.
How do electrons move between proteins?
The proteins act like factory workers, passing down the electrons in a chain. As the electrons pass through , four proteins use the energy stored in the electrons to move hydrogen ions into the intermembrane space.
How does oxygen affect cellular respiration?
Your body cells use the oxygen you breathe to get energy from the food you eat. This process is called cellular respiration. During cellular respiration the cell uses oxygen to break down sugar. When the cell uses oxygen to break down sugar, oxygen is used, carbon dioxide is produced, and energy is released.
What is oxygen needed for in cellular respiration?
Aerobic cellular respiration is the process by which cells use oxygen to help them convert glucose into energy. This type of respiration occurs in three steps: glycolysis; the Krebs cycle; and electron transport phosphorylation.
What is the role of oxygen in aerobic cellular respiration?
Oxygen is the final electron acceptor at the end of the electron transport chain of aerobic respiration. In the absence of oxygen, only a few ATP are produced from glucose. In the presence of oxygen, many more ATP are made.
What are the advantages of aerobic respiration?
A major advantage of aerobic respiration is the amount of energy it releases. Without oxygen, organisms can split glucose into just two molecules of pyruvate. This releases only enough energy to make two ATP molecules. With oxygen, organisms can break down glucose all the way to carbon dioxide.
What is the final destination of oxygen in the respiration process?
The oxygen you breathe in goes into your lungs and passes into your blood from there. It is then transported to all the cells in your body through your bloodstream. The lungs are located in the chest region, protected by the ribs in the rib cage.
What is the correct pathway of oxygen?
During gas exchange oxygen moves from the lungs to the bloodstream. At the same time carbon dioxide passes from the blood to the lungs. This happens in the lungs between the alveoli and a network of tiny blood vessels called capillaries, which are located in the walls of the alveoli.
What is the correct pathway of oxygen to the lungs?
Respiratory System: Pathway of air: nasal cavities (or oral cavity) > pharynx > trachea > primary bronchi (right & left) > secondary bronchi > tertiary bronchi > bronchioles > alveoli (site of gas exchange)
Which stage of cellular respiration uses oxygen?
The other three stages of cellular respiration—pyruvate oxidation, the citric acid cycle, and oxidative phosphorylation—require oxygen in order to occur. Only oxidative phosphorylation uses oxygen directly, but the other two stages can’t run without oxidative phosphorylation.
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.
Where does stage 1 and stage 2 of cellular respiration occur?
The space between the inner and outer membrane is called the intermembrane space. The space enclosed by the inner membrane is called the matrix. The second stage of cellular respiration, the Krebs cycle, takes place in the matrix. The third stage, electron transport, takes place on the inner membrane.
How does Stage 2 of cellular respiration benefit a cell?
In eukaryotes, the second stage of cellular respiration takes place in the matrix of the mitochondria, which plays a major role in the production of ATP molecules within the cells. In this stage, a large amount of energy (ATP molecules) is produced after the complete oxidation of nutrients.
Where do the steps of cellular respiration occur?
The process begins in the cytoplasm and is completed in a mitochondrion. Cellular respiration occurs in three stages: glycolysis, the Krebs cycle, and electron transport. Glycolysis is an anaerobic process. The other two stages are aerobic processes.
What 2 products made during cellular respiration gets used in photosynthesis?
Photosynthesis makes the glucose that is used in cellular respiration to make ATP. The glucose is then turned back into carbon dioxide, which is used in photosynthesis. While water is broken down to form oxygen during photosynthesis, in cellular respiration oxygen is combined with hydrogen to form water.
Where does photosynthesis and cellular respiration occur?
Photosynthesis occurs in the chloroplasts, whereas cellular respiration occurs in the mitochondria.
