|
Metabolism
|
The sum of the chemical reactions that occur within a living cell
|
|
|
Catabolic
|
breaking down large molecules into smaller ones.They release energy.
|
|
|
Anabolic
|
Build large molecules from simpler ones. Requires energy
|
|
|
A metabolic pathway
|
a sequence of enzymatically catalyzed cemical reactions in a cell. They are determined by enzymes. All enzymes are proteins
|
|
|
Characteristics of Enzymes
|
Speed up reactions (catalysts) by increasing rates of reaction, by lowering activation energy to allow molecules to react without increasing temp inside cell. They are highly selective. Each enzyme will only catalyze one type of reaction. They are needed in small amounts. They are reusable
|
|
|
Difference between virus and bacteria
|
-structure
-viruses dont have enzymes |
|
|
Factors that affect enzymes
|
-temperature
-ph -substrate concentration -inhibitors -enzyme structure |
|
|
Enzymes
|
some made of proteins only
others have apoenzyme and cofactor -apoenzyme (protein portion) -cofactor (non protein portion) |
|
|
Aerobic Respiration
|
Carbohydrates, lipids, and proteins are used on energy sources (glucose as primary source.)
Oxygen is the final electron acceptor |
