Animal cells are able to move because they do not have a cell wall like a plant does. Hope this helps, good luck!
<u><em>-Describe the electron transport chain. What part of the cells does hit reaction take place in?
</em></u>
The electron transport chain is A group of compounds that pass electron from one to another via redox reactions coupled with the transfer of proton across a membrane to create a proton gradient that drives ATP synthesis. The electron transport chain occurs in the inner membrane of the mitochondria.
<u><em>-What molecule stores the energy that is generated during cellular respiration?
</em></u>
Cells create energy by breaking down the ATP molecules. Thus, cellular respiration is the utilization of oxygen for the synthesis of ATP. Glucose is broken down to supply energy for cellular respiration.
Explanation:
The molecule is the smallest unit of the substance that retains its characteristic properties. The macromolecule is such a unit but is considerably larger than the ordinary molecule, which usually has a diameter of less than 10 angstroms (10−6 mm).
The correct answer is option A. They either match up with a receptor molecule on the surface of the cell or enter the cell through the membrane.
The intercellular signals are the signals, which transfer the signals from one cell to the another and the intracellular signals are those signals, which carries message within the cell.
The intercellular signals may or may not be transferred through the gap junctions. The chemical signals are one of the type of the cell signals. The chemical signalling molecules generally have a receptor on the cells, where these molecules can bind and can be cause the activation of the cell. The chemical signals can also enter into the cells through active transport and facilitated diffusion. So, these type of transports does not go through the Gap junction.
D nuclear membrane since bacteria is a prokaryote which means it does not have a nuclear membrane
