Terms in this set (14)
In cells, the energy available in foods is used to make an energy-rich compound called:
The first step in releasing the energy of glucose in the cell is known as:
The process that releases energy from food in the presence of oxygen is:
Which organisms (on page 237) perform cellular respiration?
all of them
The net gain of energy from glycolysis is:
2 ATP molecules
Because permentation takes place in the absence of oxygen, it is said to be:
The Krebs cycle takes place within the:
The electron tranport chain uses the high-energy electrons from the Krebs cycle to:
convert ADP to ATP
A total of 36 molecules of ATP are produced from 1 molecule of glucose as a result of:
During heavy exercise, the buildp of lactic acid in muscle cells results in:
How is glucose changed during glycolysis?
broken in half
What are two pathways that might follow glycolysis?
Ferm=no oxygen Cell respiration=with oxygen
Use formulas to write a chemical equation for cellular respiration. Kabel the formulas with the names of the compounds
C6 H12 O6 + O2 ----------> CO2 + H2O + ATP
Write equations to show how lactic acid fermentation compares with alcoholic fermentation. Which reactants (s) do they have in common
lactic acid=pyrovic acid + NADH------> Lactic acid NAD
alcoholic= Pyrovic Acid + NADH -------->alcohol +CO2 + NAD
