A glucose molecule is completely broken down upon completion of glycolysis and the citric acid cycle. however, these two process
Blababa [14]
In both the process of glycolysis and the citric acid cycle; yes ATP is produced albeit in a very low amount. Another byproduct of these pathways are the production of reducing compounds such as reduced nicotinamide adenine dinucleotide (NADH) and reduced flavin adenine dinucleotide (FADH). These reducing compounds are used in the electron transport chain to produce a proton gradient, and with a proton gradient, the enzyme ATP synthase will synthesize ATP from ADP and inorganic phosphate.

A decline in sensory responsiveness that occurs when a stimulus is unchanging or repetitive is called _______________.
nikklg [1K]

Answer:

Sensory Adaption

Explanation:

Stimuli, both external and internal, are sensed with the help of sensory receptors. These sensory receptors sense the change in internal or external conditions called stimuli and send the information to the central nervous system. The sensory information is processed and interpreted in the central nervous system which in turn makes a person aware of the sensed stimuli.

However, the constant presence of the same stimulus does not trigger the firing of the action potential as it occurred during the first few encounters. This is called sensory adaption. For example, chirping of birds is apparent when a person enters the countryside but becomes less apparent after a few days due to sensory adaption of ears.
