Summary of hearing: Vibrations cause the cochlea’s membrane to shake. This causes ripples in the ____________, bending the _____
mash [69]

Answer:

1) Basilar membrane

2) Stereocilia or hair cells

3) Nerve cells

4) Auditory

5) Temporal lobe

Explanation:

Basilar membrane: located inside of the cochlea which is located in the inner ear. This membrane separates two tubes that is filled with liquid which is also important for hearing.  

Hair cells: Connected to the basilar membrane and they acts as sensory receptors which can catch movements (ripples) in the basilar membrane and pass this message to the neurons.

Nerve cells: One of the main cell types in the brain, which are responsible for signal transfer.

Auditory cortex: This part of the brain is located in temporal lobe and handles the auditory information.

What membrane activities requires energy from atp hydrolysis?
NikAS [45]

Answer:

active transport, like Na + ions leaving the cell

Explanation:

The active transport requires an energy expenditure to transport the molecule from one side of the membrane to the other, but the active transport is the only one that can transport molecules against a concentration gradient, just as the diffusion facilitated the active transport is limited by the number of transport proteins present.

Two major categories of active, primary and secondary transport are of interest. The primary active transport uses energy (generally obtained from ATP hydrolysis), at the level of the same membrane protein producing a conformational change that results in the transport of a molecule through the protein.

The best known example is the Na + / K + pump. The Na + / K + pump performs a countertransport ("antyport") transports K + into the cell and Na + outside it, at the same time, spending on the ATP process.

The secondary active transport uses energy to establish a gradient across the cell membrane, and then uses that gradient to transport a molecule of interest against its concentration gradient.
