BIO PRACTICAL CELLULAR RESPIRATION

Anaerobic Fermentation

-ATP-generating process that involves the breakdown of glucose to either ethanol or lactate (NO oxygen products) -Occurs in the cytoplasm -Generates much lower levels of ATP

Ideal Gas Law - Procedure 2

-PV=nRT -Respirometers: submerged in water bath at a constant temperature; volume is constant, R is kept constant -Pressure of gas in respirometer is directly proportional to number of molecules of gas present -absolute pressure of the gas=number of gas molecules

1.After death cellular metabolism continues for ______ 2.This leads to an accumulation of ________ in cells. 3.Which in turn leads to a ____________ intercellular pH. 4.This will cause ___________ to rupture and autolysis of tissue 5.The entire process will __________ if the environmental temperature is warm

1.4-10 minutes 2.CO2 3.lower 4.Lysosomes 5.speedup

Aerobic Cellular Respiration

An ATP-generating process that involves the complete breakdown of glucose to carbon dioxide and *water Oxygen is the final electron acceptor (to form water)

Process is anaerobic.

Both Ethanol fermentation and Lactic Acid fermentation

In the experiment where CO 2 production is measured with a respirometer what will be left out of the negative control?

Glucose

Procedure 2

measuring oxygen consumption in germinating and non germinating seeds

In the experiment where O 2 consumption is measured with a respirometer the CO 2 is absorbed by KOH. This ______________ the number of gas molecules in the respirometer thereby _____________ the pressure in the respirometer.

reduces, reducing

In cellular respiration seeds consume...

seeds consume O2 and release CO2. we add KOH to absorb the CO2
