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?
Nitrogen-Building block of proteins
What part of the pathway to produce platelets is shared with other formed elements?
hematopoietic stem cell (hemocytoblast)
Is oxygen produced when humans do cell respiration?
Oxygen is used and CO2 is produced
What gas leaves the cell as waste?
oxygen
Why can oxygen diffuse across a cell membrane but a protein can't?
Oxygen is much smaller than a protein
When oxygen delivery to the cell is impaired which pathway is used for energy production?
anaerobic respiration
What factor can determine which pathway a cell might follow aerobic or anaerobic in glycolysis?
Oxygen
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 factor can determine which of those pathways a cell might follow?
whether or not the pathway needs oxygen or not
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 is oxygen being passed from the blood to a bicep muscle cell an example of?
Internal respiration
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?
Nitrogen-Building block of proteins
Does oxidation of pyruvate need oxygen to occur?
Yes.In a cell the only pathway that oxidizes pyruvate is the series of reactions in the mitochondria that lead eventually to complete oxidation to carbon dioxide and water. This process requires oxygen as a final acceptor of the hydrogen atoms removed during this oxidation.The complete pathway involves the link reaction and the reactions of the Krebs (citric acid) cycle.
What is insulin's target pathway?
cytoplasm to ER to outside the cell
What is the targeted pathway for insulin?
ER>Golgi>Outside of the cell.
What is the correct pathway for transmission of visual information?
photoreceptor to the bipolar cell to the bipolar cell t
What is the pathway of an oxygen molecule from the atmosphere to its combination with a hemoglobin molecule?
Oxygen reaches the hemoglobin in the blood cells by entering the lungs. The key area of the lungs where the transfer of oxygen and carbon dioxide is made is called the alveoli. The Alveoli has very thin cell walls which allow oxygen and carbon dioxide to pass freely in and out of the blood stream.
