"Conservation of energy" refers to the fact that.....
  • they consume energy to build up polymers from monomers
  • energy cannot be created or destroyed but can be converted from one form to another.
  • enzymes increase the rate of a reaction by lowering the activation energy barrier
  • increase the rate of a reaction without being consumed by the reaction
Energy is observed in two basic forms: Potential and kinetic. What of the following correctly matches these forms with a source of energy?A) the heat released from a living organism: potential energyB) the motion of individual molecules: potential energyC) the covalent bonds of sugar molecule: potential energyD) the energy associated with gradient of ions across a membrane: kinetic energyE) the energy related to the height of a bird above the ground: kinetic energy
  • they consume energy to build up polymers from monomers
  • is involved in the catalytic reaction of the enzyme
  • The covalent bonds of a sugar molecule: potential energy
  • increase the rate of a reaction without being consumed by the reaction
The process of cellular respiration, which converts simple sugars such as glucose into CO2 and water, is an example of?A) a pathway that converts organic matter into energyB) a catabolic pathwayC) a pathway that occurs in animal cells but not plant cellsD) an endergonic pathwayE) a pathway in which the entropy of the system decreases
  • a molecule of glucose
  • activation energy
  • anabolic reactions
  • A catabolic pathway
