Answer:
Oxygen is needed to help the process of turning glucose into ATP. The initial step releases just two molecules of ATP for each glucose. The later steps release much more ATP.
Explanation:
In stage one, glucose is broken down in the cytoplasm of the cell in a process called glycolysis.
In stage two, the pyruvate molecules are transported into the mitochondria. The mitochondria are the organelles known as the energy "powerhouses" of the cells (Figure below). In the mitochondria, the pyruvate, which have been converted into a 2-carbon molecule, enter the Krebs cycle. Notice that mitochondria have an inner membrane with many folds, called cristae. These cristae greatly increase the membrane surface area where many of the cellular respiration reactions take place.
In stage three, the energy in the energy carriers enters an electron transport chain. During this step, this energy is used to produce ATP.
Answer:
Metamorphic rock
Explanation:
When a sedimentary rock goes deep underground, it experiences heat and pressure. This distorts the rock and turns it into a metamorphic rock
Answer: i cinque isomeri possibili per l'esano sono n-esano, 2-metil pentano, 3-metil pentano, 2, 3-dimetilbutano e 2, 2-dimetilbutano. - 2-metil pentano è anche chiamato isoesano. - 2, 2-dimetil butano chiamato anche Neoesano.
Explanation:
Answer:
The correct answer is - less efficient signaling.
Explanation:
Second messengers are the molecules that help in transferring the information in the form of intracellular signal that has come from external stimulus.
Second messenger molecules should be short-lived as the concentration of these molecules should be decreased fastly so the cell can be available for other stimuli mediated by the same second messenger.
With increased lifetime, signaling will be less efficient as another stimulus cannot be detected.
Thus, the correct answer is - less efficient signaling.
