Unit 3 Flashcards
What do enzymes do
They catalyze reactions and reduce the activation energy
What are some of the biological reactions enzymes play a role in
Cellular respiration, photosynthesis, glycolysis,
What is a competitive inhibitor
They directly compete for the active site with the substrates
How do really high temperatures denature an enzyme
They disrupts the bonds between the amino acids causing the enzyme to lose its structure which in turn loses its function
How can the concentration of substrates and enzymes help or not help
The reaction depends on the relative concentration of the substrates and enzyme
What do allosteric inhibitors do
They bind to the allosteric site changing the shape of the active site
First law of TD
Energy cannot be created nor destroyed
what happens to some of the energy that we use
It becomes unusable energy which is in the form of heat
Second law of TD
That unusable energy is contributed to the entropy or disorder of the universe
Clustering of enzymes is a sequential pathway because
one product of an enzyme is being transferred to the next
Enzymes changes the what
The activation energy, not the energy of the reactants and products
Exergonic process results in a what
A net increase in energy
What contributed to the oxygen in the atmosphere
Prokaryotic photosynthesis
How did eukaryotic photosynthesis get developed
Prokaryotic photosynthetic pathways
Low ph provides what for mitochondria peforming cellular respiration.
They provide h+ ions that can contribute to the proton gradient, thus increasing the amount of atp being made
