|
|
What is the break down of complex organic compounds into simpler ones?
|
Catabolism
|
|
|
Catabolism reactions are called
|
Catabolic/degradative
|
|
|
Catabolic reactions are usually what type of reactions?
|
Hydrolytic Reactions
|
|
|
Those that require energy are called....

Anabolism
|
|
|
Those that release energy are called..
|
Catabolism
|
|
|
Metabolism is divided into what two classes of chemical reactions?
|
1. Catabolism
2. Anabolism |
|
|
Metabolism can be viewed as what?
|
An energy balancing act
|
|
|
Catabolic reactions which produce more energy than they consume are called what?
|
Exergonic
|
|
|
This is an example of what type of reaction:
When cells break down sugars into carbon dioxide and water |
Catabolism
|
|
|
What is the building of complex organic molecules from simpler ones?
|
Anabolism
|
|
|
Anabolism reactions are often called _______ or ________
|
Anabolic
or Biosynthetic Reactions |
|
|
Anabolic reactions often involve what reactions?
|
Dehydration Synthesis Reactions
|
|
|
What is the role of ATP in coupling anabolic and catabolic reactions?
|
When complex molecules are split apart (catabolism). Some of the energy is transferred to and trapped in ATP, and the rest is given off as heat.
When simple molecules are combined to form complex molecues (anabolism), ATP provides the energy for synthesis and again some energy is given off as heat. |
|
|
__________ is the principal properties of a group of proteins involved in almost all biologically important chemical reactions
|
Enzymes
|
|
|
A cell's _______ ________ (sequence of chemical reactions) are determined by its enzymes, which are in turn determined by the cell's genetic makeup.
|
Metabolic Pathways
|
|
|
Which molecule facilitates the coupling of anabolic and catabolic reactions?
|
ATP
