Test 1 Flashcards
What happens during dehydration synthesis? What about hydrolysis?
An enzyme joins two monomers. Water is a byproduct. In hydrolysis, the polymers break back into monomers using water.
What might be a products of hydrolysis reactions occuring on a triglyceride?
Fatty acids and glycerol.
What happens at receptor proteins?
Hormones bind there.
What do transport proteins do?
Allows ions (or other things that need aid) move in and out of the cell.
What do enzymes do?
These proteins help catalyze chemical reactions.
What might happen with recognition proteins?
A woman has a disorder causing her immune system to attack her own cells. She may have a problem with these proteins.
What do adhesion proteins do?
Allow cells to stick together.
What is the monomer of a protein?
An amino acid.
In a ____ reaction, an electron acceptor gains electrons and their energy.
Reduction
What is cell theory?
That all cells are made of one or more cells, the fundamental units of life.
Movement would not be considered a characteristic of what?
A characteristic of life
In a ____ reaction, a molecule, atom, or ion loses electrons and _____.
Oxidation, energy
In a ______ reaction, an electron acceptor gains electrons and their energy.
Reduction
When these electron transferring reactions occur together (oxidation and reduction), they are called ____ reactions, and they play a vital role in cellular respiration and photosynthesis.
Redox
Why is cellular respiration important?
It generates ATP, which cells can use to do work.
