A neuron can receive thousands of EPSPs from different neurons, and responds by triggering or not triggering an action potential
Korvikt [17]

Answer:

The addition and response to the net effect of postsynaptic potentials is called Spatial summation

Explanation:

Signal summation occurs when impulses received by a neuron are eummed together to reach the excitation threshold to fire a neuron. It occurs at the axon hillock of a neuron. Signal summation occurs since each neuron is connected to many other neurons, often receiving multiple impulses from them, both excitatory and inhibitory.

Signal summation can either be temporal or spatial.

Temporal summation, occurs when impulses received at the same place on the neuron in close temporal succession add up to initiate an action potential in the neuron.

Spatial summation occurs when impulses received simultaneously at different places on the neuron add up to initiate an action potential in the neuron.

Milk is converted to yogurt under certain conditions when the microorganisms in the milk produce acid. Which of these processes
oee [108]

Milk is converted to yogurt under certain conditions when the microorganisms in the milk produce acid. Which of these processes would you expect to be key in the production of yogurt?

a. Photosynthesis

b. Lactic acid fermentation

c. Krebs cycle

d. Alcoholic fermentation

Answer:

b. Lactic acid fermentation

Explanation:

Lactic acid fermentation occurs when pyruvate formed by glycolysis is reduced into lactate under the anaerobic conditions. The NADH serves as an electron donor for the reduction of pyruvate into lactic acid. Lactic acid bacteria are the anaerobic bacteria that ferment the milk sugar lactose into lactic acid. This converts the milk into yogurt. <em>Lactobacillus, Streptococcus salivarius</em>, etc. are mostly responsible for the conversion of milk into yogurt.
