ATP yield per molecule of glucose at each stage of cellular respiration (blank ATP total per glucose molecule)
As electrons move through the ETC, they provide blank for the proton pumps move H+ across the inner mitochondrial membrane
a macromolecule that acts as a catalyst- a substance that can speed up a reaction without being consumed.
Energy cannot be created nor destroyed. The energy of the universe is constant; it can only be transferred or transformed.
Change to the molecular structure of an enzyme will result in a change in?
reactions that break down complex molecules into simpler compounds
absorbs energy from its surroundingsEx: Photosynthesis which uses light energy to build glucose molecules
The enzyme changes shape due to chemical groups when the substrate enters active site- "Clasping handshake"
releases energyEx: Cellular Respiration which breaks down sugars to produce ATP
energy released from catabolic reactions can be used to drive anabolic reactions, exergonic reactions drive endergonic reactions
Every energy transfer or transformation increases the entropy (molecular disorder) of the universe.Ex: The bear releases heat, CO2 and H20 which increases disorder in the universe
An organism's blank is the total amount of energy an animal uses in a unit of time
reactions that build molecules from simpler compounds
