Turgid: Distended or swollen, especially due to high fluid content.
Turgor pressure (turgidity) pushes the cell membrane against the cell wall. Caused by the osmotic flow into vacuole. Healthy plant cells are turgid and plants rely on turgidity to maintain rigidity. has cell walls: plant, bacteria, and fungi cells as well as those protist cells which have cell walls Caused by osmotic flow of water from area of low solute concentration outside of the cell into the cell's vacuole, which has a higher solute concentration. this phenomenon is not observed in animal cells which have no cell walls to prevent them from being burst by the flow of water into the cell and must either continually pump out water or live in an isotonic solution where there is no osmotic pressure.

Example: Ethanol is metabolized in the body by oxidation to acetaldehyde, which is in turn further oxidized to acetic acid by aldehyde oxidase enzymes. Normally, the second reaction is rapid so that acetaldehyde does not accumulate in the body. A drug, disulfiram (Antabuse) inhibits the aldehyde oxidase which causes the accumulation of acetaldehyde with subsequent unpleasant side-effects of nausea and vomiting. This drug is sometimes used to help people overcome the drinking habit.
4
What Is ATP? Energy used by all cells Adenosine TriPhosphate
Organic molecule containing high-energy phosphate bonds
5
Chemical Structure of ATP
Base 3 Sugar
6
What Does ATP Do for You? It supplies YOU with ENERGY!
7
How Do We Get Energy From ATP?
By breaking the high- energy bonds between the last two phosphates in ATP
8
What is the Process Called?
HYDROLYSIS (Adding H2O)
9
What do you need to break down ATP?
An Enzyme! ATPase
10
What do you need to make ATP?
The reverse of the previous process occurs. Another Enzyme is used! ATP Synthase
11
The ADP-ATP Cycle ATPase ATP Synthase
12
When is ATP Made in the Body?
During a Process called Cellular Respiration that takes place in both Plants & Animals
14
ATP Cartoon Create a 4 panel cartoon showing how ADP and ATP work in a cell. Include the following: ATP ADP P (phosphate) ATPase & ATP synthase Energy
