The correct question is: Does respiration and fermentation involve active transport?
Active transport is a fundamental process that is pertinent to many other cellular processes. In nature, matter wants to equilibrate, gases, molecules, and ions all want to homogenize. Active transport opposes this; it is the movement of ions, gases, and molecules from areas of low concentration to areas of high concentration. Active transport is the reason life has been described as seemingly violating the 2nd Law of Thermodynamics ( this is not actually the case) where the change in entropy of a system must increase after any process.
In cellular respiration a chain of proteins is reduced by molecules made during glycolysis and the citric acid cycle. The electron that is handed off at the top of this electron transport chain of proteins is electrically attracted to the oxygen molecule housed in a protein at the end of the chain. The entire purpose of this flow of electrons is to power the active transport of protons from the cytoplasm to the inner mitochondrial membrane (or in the case of prokaryotes, from the exterior of the cell to the interior of the cell). The energy of this proton concentration gradient is then stored in molecules called ATP as the protons flow down the gradient and through an enzyme called ATP-synthase.
Fermentation occurs in the absence of oxygen as the final electron acceptor of the electron transport chain. While fermentation does not involve the active transport of protons like respiration it does require the active transport of glucose. A higher concentration of glucose must be maintained within the confines of a cell than in the cells external environment. This is especially the case with bacteria and other prokaryotes that are not privileged like the intestinal cells of animals which our regularly surrounded by glucose.
If you dig deep you will find that most cellular processes involve active transport in some direct or indirect way.

What prevents active transport taking place?
Believe it or not, cyanide kills us by inhibiting active transport, to such an extent that substances can no longer be transferred across cell membranes. This is one example of a substance that stops the process of active transport dead in its tracks.
What process requires cells to expend energy in the form of ATP?
Active transport processes, such as the sodium-potassium pump, require cells to expend energy in the form of ATP. The energy from ATP is needed to move molecules or ions against their concentration gradient, from an area of lower concentration to an area of higher concentration.
How does photosynthesis and respiration use active transport?
Both processes use active transport to move molecules across cellular membranes against their concentration gradient. In photosynthesis, active transport is used to move ions across the thylakoid membrane to create a proton gradient for ATP production. In respiration, active transport is involved in pumping hydrogen ions across the inner mitochondrial membrane to generate ATP through oxidative phosphorylation.
Active transport involves what?
Active Transport requires first of all Energy which is obtained from respiration and secondly a selectively permeable membrane through which movement of materials can take place.
What 2 transport processes use carrier proteins?
Two transport processes that use carrier proteins are facilitated diffusion and active transport. In facilitated diffusion, carrier proteins help move molecules across the cell membrane down their concentration gradient, while in active transport, carrier proteins help move molecules against their concentration gradient by using energy.
What processes can take place in a root hair cell when oxygen is not available?
active transport and osmosis
Does diffusion and active transport use oxygen?
Diffusion does not require energy and can occur without the need for oxygen. Active transport, on the other hand, requires energy in the form of ATP and does not directly involve the use of oxygen, although oxygen is essential for producing ATP through cellular respiration.
What requires ATP cellular energy?
Processes that require ATP cellular energy include muscle contraction, active transport of molecules across cell membranes, and cellular respiration to generate energy in the form of ATP. Additionally, ATP is needed for biosynthesis of molecules, DNA replication, and cell division.
Does active transport involve the movement of molecules against the concentration gradient?
Yes, active transport involves the movement of molecules against the concentration gradient.
What organelle produce the energy required in active transport?
Mithocondria
Does osmosis involve transport proteins?
No, osmosis does not involve transport proteins. Osmosis is the passive movement of water across a selectively permeable membrane in response to a concentration gradient. Transport proteins are involved in facilitated diffusion and active transport processes.
In what ways are active transport and facilitated diffusion similar?
Active transport and facilitated diffusion are similar in that they both involve the movement of molecules across a cell membrane, but they differ in that active transport requires energy input from the cell, while facilitated diffusion does not.

Materials can be moved from a low concentration to a high concentration through?
active transport processes like primary active transport or secondary active transport, which require energy to move molecules against their concentration gradient. This can involve the use of transport proteins or ion pumps in the cell membrane.
