Describe the pathway of electrons from the time they enter the intermembrane space of the mitochondrion to the time they are returned to the inside of the mitochondrion?
Electrons enter the intermembrane space of the mitochondrion through Complex III in the electron transport chain. They then travel to Complex IV, where they reduce oxygen to form water. Once the electrons have been used in the transport chain, they are returned to the inside of the mitochondrion by pumping protons out of the matrix during oxidative phosphorylation, creating a proton gradient that drives ATP synthesis.
What stopps electrons from passing through a material?
magnetism
How many electrons pass through an electric bulb in one minute if 300 A current is passing through?
To determine the number of electrons passing through the bulb in one minute, we need to use the formula: Number of electrons = (current * time)/(charge of one electron) Given current = 300 A and time = 1 minute, we can calculate the number of electrons passing through the bulb. Charge of one electron is approximately 1.6 x 10^-19 Coulombs.
Which accumulates in the inter membrane space of the mitochondrion during electron transport?
During electron transport in the mitochondrion, protons (H+) accumulate in the intermembrane space. This happens as electrons are transferred through the electron transport chain, creating a proton gradient across the inner mitochondrial membrane. This gradient of protons is later utilized by ATP synthase to generate ATP through oxidative phosphorylation.
What happens when electricity flow through wires?
Electrons move through the wire
What is the number of electrons flowing through the wire?
The number of electrons flowing through a wire depends on the current passing through it. One ampere of current corresponds to approximately 6.24 x 10^18 electrons flowing through the wire per second.
Does electromagnetism stop us falling through floor?
No, electromagnetism does not prevent us from falling through the floor. The repulsion between electrons in our body and the electrons in the floor creates the sensation of solidity, keeping us from passing through it.
Why electrons will not flow through rubber?
Rubber is an insulator. It's made mostly of hydrocarbons that don't easily ionize, and aren't good at passing electrons around.
What is a transmission electron microscope image formed by?
electrons passing through ultra thin samples of cells or tissues
What happens to the electron beam after it has passed through the specimen in an electron microscope?
After passing through the specimen in an electron microscope, the electron beam is detected by a sensor, which generates an image based on the interactions of the electrons with the specimen. The image can reveal detailed information about the specimen's structure, composition, and morphology.
The mitochondrion is the place in the cell where what happens?
The mitochondrion is where cellular respiration occurs, converting nutrients such as glucose into a usable form of energy called ATP through a series of biochemical reactions. This process plays a crucial role in generating energy for the cell to carry out its functions.
How many electrons are passing through a section of a conductor per second if the current is two amperes?
In a conductor, the flow of current is due to the movement of electrons. One ampere (1 A) is equivalent to the passage of 6.242 x 10^18 electrons per second. Therefore, if the current is two amperes, the number of electrons passing through a section of the conductor per second would be 2 x 6.242 x 10^18 = 1.2484 x 10^19 electrons.
