<span>Cell walls are made of cellulose which is made up of a sugar that is not used for energy. IT provides structure for the cell with this in mind it can be flexible and sometimes rigid. They are found in plant cells as well as other organisms. Bacteria and fungi also have cell walls. Some others include unicelluar organisms such as prokaryotes and in some cases eukaryotic cells.</span><span />
the arrow will point upwards because the active transport is the transport against concentration (from low concentration to high concentration) gradient with the help of energy derived from ATP

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.
