Write the overall equation for cell respiration. What is the goal of cell respiration?
|
C(6)H(12)O(6)+6O(2)-->6CO(2)+6H(2)O+energy
Goal: to release energy from food |
|
Describe Glycolysis...
|
Starts with 6-Carbon compound(glucose)
2 ATP activate glucose then splits into two 3-carbon compound results: 2 pyruvate, 4 ATP, 2 NADH occurs in cytoplasm |
|
Describe Kreb's cycle...
|
occurs in mitochondrium (matrix)
pyruvate enters through transport protein then converted into CoA (gives 2 carbons) CO(2) and NADH produced At the end, 3 C0(2) produced, 4 NADH, FADH(2), 1 ATP |
|
Electron Transport Chain...
|
occurs in mitochondrium (cristae)
Starts with NADH loses electron which carries hydrogens though and forms H(2)O FADH(2) loses electron which carries H through and forms another H(2)O then b/c of high concentration, H moves back and ADP takes H and forms 3 ATPs |
|
Where does each reaction take place?
|
glycolysis: cytoplasm
Kreb's: mitochondrium=matrix electron: mitochondrium=cristae |
|
Explain the importance of FADH(2) and NADH to the electron transport chain.
|
These two molecules are electron acceptors and hold the electrons until they can be made into ATP.
|
|
Relate the electron transport chain to the creation of a hydrogen ion gradient. How is this gradient used to generate ATP?
|
As the FADH(2) and NADH move the electrons around it increases the gradient b/c there are more Hydrogens on one side. This leads to the movement of the hydrogens back into the matrix therefore creating the ATP.
|
|
Explain the importance of fermentation when the cell becomes anaerobic.
|
Fermentation allows the process of cell respiration to continue without oxygen.
|
|
What is the significance of photosynthesis?
|
Photosynthesis takes the energy and makes it into food.
|
|
What is the relationship between autotrophs and heterotrophs?
|
Autotrophs are the organisms that make their own food. Also called producers. Hetertrophs eat autotrophs.
|
|
What is the relationship between photosynthesis and cellular respiration in plants?
|
Opposties. taking energy, releasing energy.
|
|
What is ATP?
|
ATP is a protein that allows H ions to pass through it and takes ADP and forms ATP.
