Explain what happens to animal cells if they are put in fresh water
neonofarm [45]
They will actually explode or burst

So What happens is the pure water outside has a high water potential while the cytoplasm inside the animal cell is a low water potential, water will diffuse down a water potential gradient through the semi-permeable membrane of the animal cell and cause the cell to swell (inflate like a fully-blown balloon), the result is that the delicate, elastic cell membrane<span> can't tolerate the internal pressure coming from the cytoplasm so it tears causing the cell to burst.</span><span>

What is the differences between cellular respiration and respiration
3241004551 [841]

Think of respiration as ‘cellular respiration,’ which is the process by which the body extracts energy from glucose molecules. Breathing is the mechanism of the lungs that brings oxygen into the body and expels carbon dioxide

Respiration is a vital way for the cells of plants and animals to obtain and utilize energy. Without this energy, cells in the bodies of plants and animals would fail to function and will eventually break down and die. The breaking down of sugar into energy and storing it in ATP is the key to the survival of living organisms.

The formation of ATP involves two different processes, cellular respiration and fermentation. The reactions to these processes are controlled by enzymes and involve the loss and gain of electrons.

Cellular respiration takes place in the cells of organisms using metabolic reactions and processes to convert biochemical energy from the nutrients they absorbed into ATP or adenosine triphosphate and to release waste products.

The energy derived from nutrients like sugar, amino and fatty acids, an electron acceptor which can be oxygen (used by aerobic organisms) or other inorganic donors like sulfur, metal ions, methane, or hydrogen (used by anaerobic organisms) are stored in ATP and used for biosynthesis, locomotion and to transport molecules in cell membranes.

Cellular respiration can be aerobic or anaerobic. Aerobic respiration requires oxygen to generate ATP and plants and animals use this in utilizing the energy they received.
