Oxygen enters the body through the respiratory system, where it is inhaled and travels down the trachea into the lungs. In the lungs, oxygen diffuses into the bloodstream through the alveoli. The oxygen-rich blood is then pumped by the heart to various parts of the body through arteries, eventually reaching individual cells where it is used in cellular respiration to produce energy.
What else can I help you with?
A radioactive element is sometimes used to trace the pathway of chemical reactions in the cell If newly synthesized proteins are radioactive the radioactive element used could be?
The radioactive element used to trace the pathway of chemical reactions in cells for newly synthesized proteins is typically sulfur-35 (35S) or carbon-14 (14C). These isotopes are incorporated into proteins during synthesis, allowing researchers to track their movement and interactions within the cell.
Why is radioactive sulfur used?
Radioactive sulfur is used in scientific research to trace the pathway of sulfur in biological systems and to understand sulfur metabolism in different organisms. It can help researchers study processes like protein synthesis, enzyme activity, and cell division.
What part of the pathway to produce platelets is shared with other formed elements?
The pathway to produce platelets involves the common precursor cell called the megakaryocyte. This cell is also involved in the production of red and white blood cells. They differentiate into platelets through a process of budding off fragments of their cytoplasm.
How many oxygen molecules sickle cell hemoglobin carry?
Sickle cell hemoglobin can carry one oxygen molecule.
Why does oxygen diffuse into cell?
Oxygen diffuses into cells due to differences in oxygen concentration between the environment and the cell. Cells consume oxygen during cellular respiration to produce energy, creating a concentration gradient that drives oxygen diffusion into the cell. Oxygen then binds to hemoglobin in red blood cells for transport to tissues throughout the body.
What factor can determine which of those pathways a cell might follow?
The factors that can determine which pathway a cell might follow include external signals from the cell's environment, internal genetic and epigenetic regulation, and cell-to-cell communication. These factors can influence a cell's decision to divide, differentiate, or undergo programmed cell death.
What factor can determine which pathway a cell might follow aerobic or anaerobic in glycolysis?
Oxygen
When oxygen delivery to the cell is impaired which pathway is used for energy production?
anaerobic respiration
Trace the pathway of exporting protiens from the cell?
Examples of secretory proteins are collagen, insulin, and digestive enzymes of the stomach and intestine.
What factore determine which pathway a cell might follow after glycolosis?
If enough oxygen is available, the product of glycolysis, pyruvate, will be further broken down to CO2 and water. This requires oxygen and occurs partly in the mitochondrion. If not enough oxygen is available, the pyruvate will be converted to lactic acid, which causes muscular pain. This pathway also produces less energy for the cell.
What are the 2 metabolic pathways a cell can use and what determines which pathway is being used?
Cells can use aerobic (oxidative) and anaerobic (glycolytic) pathways. The availability of oxygen determines which pathway is being used; aerobic pathways are utilized in the presence of oxygen, while anaerobic pathways are used when oxygen is limited. Oxygen is essential for the electron transport chain in aerobic metabolism, while glycolysis can proceed in the absence of oxygen.

The radioactive element used to trace the pathway of chemical reactions in cells for newly synthesized proteins is typically sulfur-35 (35S) or carbon-14 (14C). These isotopes are incorporated into proteins during synthesis, allowing researchers to track their movement and interactions within the cell.
What metabolic pathway in a cell does not require oxygen?
During recovery, when oxygen becomes available, NAD+ attaches to hydrogen from lactate to form ATP. In yeast, the waste products are ethanol and carbon dioxide. This type of fermentation is known as alcoholic or ethanol fermentation. The ATP generated in this process is made by substrate-level phosphorylation, which does not require oxygen.
What is the targeted pathway for insulin?
ER>Golgi>Outside of the cell.
What is insulin's target pathway?
cytoplasm to ER to outside the cell
What is the internal delivery of a cell?
The endoplasmic reticulum is the internal delivery system for a cell.
What is the correct pathway for transmission of visual information?
photoreceptor to the bipolar cell to the bipolar cell t
