One reason that atp is a source of energy is that the products of atp hydrolysis have less free energy
Svetlanka [38]
Correct! molecules going through reactions always want to form products that are less in energy so that molecules can be more stable. ATP molecule when made is not very stable and so it is high in energy. So when hydrolyzed, it breaks down to something simple and releases energy and achieves a less free energy (deltaG) state

Convention cells hbnmb,
slamgirl [31]

Answer:

convention cells

Explanation:

In the field of fluid dynamics, a convection cell is the phenomenon that occurs when density differences exist within a body of liquid or gas. These density differences result in rising and/or falling currents, which are the key characteristics of a convection cell. When a volume of fluid is heated, it expands and becomes less dense and thus more buoyant than the surrounding fluid. The colder, denser part of the fluid descends to settle below the warmer, less-dense fluid, and this causes the warmer fluid to rise. Such movement is called convection, and the moving body of liquid is referred to as a convection cell. This particular type of convection, where a horizontal layer of fluid is heated from below, is known as Rayleigh–Bénard convection. Convection usually requires a gravitational field, but in microgravity experiments, thermal convection has been observed without gravitational effects.

In an experiment on synaptic transmission, a synapse was bathed in a Ca+2- free medium that was otherwise equivalent to extracel
castortr0y [4]

Answer:

Response of the postsynaptic cell is dependent on the neurotransmitter release

Explanation:

Calcium (Ca2+) is essential for the propagation of the action potential since it is required for neurotransmitter release. When an action potential reaches the end of an axon, voltage-dependent Ca2+ channels open and Ca2+ ions bind to regulatory proteins, thereby initiating the release by exocytosis of neurotransmitters contained in the presynaptic vesicles at the synapse and modulating the transmission of a signal to another neuron (i.e. the postsynaptic site).
