This is a type of protein found in the cell membrane, which regulates the coming and going of substances into or out of the cell

natita [175]

Answer:

Gated ion-channels

Explanation:

These ion channels are protein molecules that act as a passageway which span across the cell membrane allowing the movement of ions from one side of the membrane to the other. They possess the ability to open and close in response to either chemical or mechanical signals.They possess a fluidic pore, which becomes available to ions after a conformational change in the protein structure has been activated causing the ion channel to open. Based on the stimulus to which they respond, ion channels are divided into three groups: voltage-gated, ligand-gated and mechano-sensitive ion channels. Channels responding to electrical (voltage-dependent ion channels), mechanical, or chemical (ligand-gated ion channels) stimuli open and allow rapid ion movement into or out of the cell, and this movement creates an electrical signals.

IF most of the energy we use on earth comes from the sun –how does that energy (light and thermal) end up

____ [38]

Answer:

1: Chemical Energy

2: Kinetic Energy

3: Electrical Energy

4: Mechanical Energy

Explanation:

1: The energy held in food is called chemical energy. It is a form of potential energy held within chemical bonds between atoms.

2: When flowing water is captured and turned into electricity, it is called hydroelectric power or hydropower. There are several types of hydroelectric facilities; they are all powered by the kinetic energy of flowing water as it moves downstream.

3: The power for lights and stuff is Electrical Energy, ofc :]

4: The chemical energy in the food gets changed into the mechanical energy of moving muscles.

Hope this helps!! :D
