Which transport process does the cell use to direct the contents of vesicles out of the cell membrane?
Exocytosis
What is needed for seed germination?
Seed germination requires the proper combination of oxygen, temperature, moisture and light. As the seed takes up water, it activates enzymes that direct the process of germination.
The production of energy-rich ATP molecules is the direct result of?
Depends on the organism slightly but the reaction of ATP synthase produces the most ATP during cellular respiration (driven by the H+ gradient generated during the electron transport chain
What is the difference between substrate level phosphorylation and chemiosmosis?
substrate level phosphorylation does not involve (electron transport chain), oxidative phosphorylation does. Substrate level phosphorylation involves the direct transfer of phosphate from a phosphate bearing molecule to ADP, thus yielding ATP. In cellular respiration, oxidative phosphorylation requires a protein, ATP synthase, to channel energy provided by a concentration of H ions; this energy results in the combining of phosphate with ADP.
Is NADH an electron acceptor?
Not exactly. It is true that NAD is formed during electron transport chain, however, it's not a direct product. NADH is an electron carrier that dumps its electron to the electron transport chain, which oxidizes it into NAD. NAD then goes back to become reduced by glycolysis or citric acid cycle.
Is active or passive transport involved?
In active transport the ATP is used to pump molecules up the concentration gradient. Transport of molecules occurs from a low concentration of solute to high concentration of solute and requires cellular energy. While passive transport involves carriers, channels, or direct diffusion through a membrane.
Which process in the water cycle requires the direct input of energy?
Evaporation.

Where to find your serial number and activation key.?
On the packaging or you can contact ADOBE direct. If you have the newest legal version then they will issue a code to active if there is an issue. This system now requires a monthly subscription rather than a direct purchase
Does active transport involve respiration and fermentation?
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.
