Answer:
The correct answer is e. the passage of electrons from one energy-generating carrier to another
Explanation:
The electron transport chain is a series of proteins and organic molecules found in the inner membrane of the mitochondria. Electrons pass from one member of the transport chain to the next in a series of redox reactions. The energy released in these reactions is captured as a proton gradient, which in turn is used to form ATP in a process called chemosmosis.
These transport molecules, in the inner mitochondrial membrane, are reduced and oxidized, accepting electrons and transferring them to the next molecule, electrons descending from high energy levels to lower ones, that is, from one energy-generating carrier to another. When lowering to other levels, energy is released that will be used in the synthesis of ATP by oxidative phosphorylation.
Answer:
B
Explanation:
Y chromosomes are the male chromosome. A person with an XY sex chromosome pair will be male while that with an XX sex chromosome pair will be female. This is because the Y chromosome has a male-determining gene called the SRY. This gene is responsible for the development of testis.
Answer:
Dead or diseased trees can serve as a food source for some birds because there are some insects which feed on these dead trees and these insects are eaten by some birds. The body of insects is made of protein so it is a good food for birds. The insects which lived in the dead and diseased trees and feed on it are termites and bugs. Termites are also known as white ants. They feed on dead bodies of plants.
Answer:
Cellular membrane.
Explanation:
In prokaryotes electron transport chain isIn prokaryotes electron transport chain is located in the cell membrane. ETC is defined as the series of complexes which helps in the transfer of electrons from electron donors to electron acceptors via reduction, and oxidation reaction couple the transfer of protons with electron transport across a member.
The primary function of the ETC is generated a transmembrane proton electrochemical gradient, such as oxidation, and reduction reaction.
