List the four steps of cellular respiration
|
1. Glycolysis-- found in cytoplasm
2. Transition step-- found in mitochondria [matrix] 3. Kreb's cycle-- found in matrix of mitochondria 4. Electron Transfer-- found in cristae of mitochondria |
|
|
What are the properties of glucose?
|
1. Major fuel for the body.
2. Ulimately delivered to and used by the body. 3. Most cells can and do use energy, but rely almost exclusively on glucose |
|
|
What is cellular respirations primary function?
|
make engery
|
|
|
What is celllular respiration?
|
process of breaking down glucose in the presence of oxygen to produce ATP engery
|
|
|
What is the chemical equation of cellular respiration?
|
Glucose+Oxygen+2ATP--->Carbon Dioxide+water+36-38ATP
|
|
|
What is glycolysis?
|
-location in cytoplasm
-no oxygen needed |
|
|
What products does glycolysis make?
|
4 ATP
2 pyruvic acid 2 NET ATP/Gained 2 NADH+H+ |
|
|
Four major steps of glycolysis.
|
1. Energy investment- sugar activation
2. sugar splitting- glucose cleavage. 3. oxidation reduction 4. energy harvest-ATP production |
|
|
Energy investment- sugar activation
|
energizing glucose by attaching 2F
|
|
|
sugar splitting- glucose cleavage.
|
1. spit the glucose
2. make 2 intermediate 3. becomes 2 pyruvic acids |
|
|
oxidation reduction
|
P-O-O-O-P+P-O-O-O-P
releasing electrons NADH+H2 [2 products] |
|
|
energy harvest-ATP
|
-(4)ATP will be formed
-(2)pyruvic acid will also be formed. 2 ATP gained |
|
|
What is the transition reaction?
|
-location-marix of mitochondria
-oxygen is required [aerobic] |
|
|
products produced by the transition reaction?
|
2 Acetyl CoA
2 CO2 2 NADH+H+ |
|
|
What is the first step [chemical reaction] of the Kreb's cycle?
|
citric acid cycle
acetyl-CoA+Oxaloaetic acid>>>Citric Acid |
