Which of the following is continually passed from one enzyme to the next during the Electron Transport Chain?
AVprozaik [17]

The correct answer is electrons.  

Electron transport chain refers to an array of complexes, which mediates electrons from electron donors to electron acceptors through redox reactions, and combines the transfer of electrons with the transfer of protons through a membrane.  

This produces an electrochemical proton gradient, which instigates the production of ATP. The ultimate electron acceptor in the electron transport chain is oxygen in aerobic respiration and sulfate in anaerobic respiration.

Select TWO events that occur when a neurotransmitter binds and activates an excitatory synapse.
andrew-mc [135]

Answer:

Key points

Neurons communicate with one another at junctions called synapses. At a synapse, one neuron sends a message to a target neuron—another cell.

Most synapses are chemical; these synapses communicate using chemical messengers. Other synapses are electrical; in these synapses, ions flow directly between cells.

At a chemical synapse, an action potential triggers the presynaptic neuron to release neurotransmitters. These molecules bind to receptors on the postsynaptic cell and make it more or less likely to fire an action potential.

the unicellular spores of the fern ceretopteris richardii are about 100 um in diameter.calculate the surface-area-to-volume rati
WINSTONCH [101]
The surface area will be:
S.A. = 6l²
S.A = 6(100 x 10⁻⁶)²

Volume = l³
Volume = (100 x 10⁻⁶)³

Surface area to volume ratio:
[6(100 x 10⁻⁶)²] / (100 x 10⁻⁶)³
S.A : Vol = 6 x 10⁴
