exam 1 pt3 Flashcards
What is it called when atoms share electrons?
covalent
Why are hydrogen bond the weakest?
hydrogens bond is 2 atoms that already in other chemical bonds.
What is when Hydrogen electrons are bonding with other things with higher electronegativity?
hydrogen bonding
Covalent molecules create what first and between other molecules are what?
molecules/ hydrogen molecules
What is based on how many electrons are on the outer shell and how ready they are to interact with other electrons based on electronegativity?
Chemical bond
What is it called when different molecules attract each other?
Adhesion
What do hydrogen bonds create? What kind of liquid molecules?
water/ polar
What makes water stick to itself?
Cohesion
What does hydrophilic dissolve in?
water
What is it called when something does not dissolve in water? / Do polar and nonpolar things mix?
Hydrophobic/ no
water is what and what kind of tendency does soap have?
Polar/ Nonpolar tendencies
What regulates temperatures expand when it freezes, and it helps with chemical reactions?
water
What is never created or destroyed? (Law of Conservation of ____)
matter
What is it when where the higher the number the lower amount of hydrogen ion. The lower number the higher hydrogen ion you get?
PH
Buffer has the power to add what ion or remove to keep them in what based on what the cell needs?
hydrogen ion/ homeostasis
A what molecule contains both carbon and hydrogen. Anything what has carbon and hydrogen. DNA and sugars are what?
organic
A what is a single unit of a carbohydrate, protein, or
nucleic acid. what join to form polymers?
Monomers
What happens when Dehydration synthesis? / What happens with Hydrolysis?
joins monomers into polymers, releases H2O. / Breaks polymers into monomers; requires H2O.
When we take individual monomers and make polymers this is called?
Dehydration synthesis.
What are simple sugars, and they also make up larger carbohydrates.
Monosaccharides
Complex carbs are broken down slower than simple carbs because why?
of more bonds.
What do Tertiary and Quaternary make the amino acid do?
Amino acid folds and be in final structure to be a functional protein.
Polysaccharides are made of a long chain of what? / Monomers that build protein are called what? How many stages does it go through?
Carbohydrates, Amino acids and they go through 4 stages.
What do you do to denature a protein?
Final structure of a protein loses its shape by adding heat or alcohol or salty solution so bacteria can’t grow.
