Consumes energy to synthesize a complex molecule
The primary manner in which cells manage their energy resources in order to do work is called energy coupling. Which of the following statements accurately defines energy coupling?
ATP allosterically inhibits enzymes in ATP-producing pathways. The result of this is called __________.
Glucose is broken down in the presence of oxygen to carbon dioxide and water.
when is all DNA copied and checked for errors?
Cytoplasm divides immediately after this period
All organisms are made up of one or more cells, all the life functions can occur within cells, and all cells come from preexisting cells
Selectively increases the rate of a reaction
At low temperatures, a particular enzyme catalyzes a reaction, but at a slow rate. At high temperatures, the enzyme is completely inactive. What statement best explains the difference in how temperature affects the function of this enzyme?
An exergonic reaction __________ free energy, and an endergonic reaction __________ free energy.
Which of the following is changed by the presence of an enzyme in a reaction?
Cells use ATP constantly, but ATP is considered a renewable resource. What process makes this possible?
The DNA is in the cytoplasm, single-called organisms(bacteria), and first type of organism to evolve/most common today
It contains the genetic instructions that cells need to make proteins
What is the product formed when oxygen is absent during cell respiration in animal cells
