- Cells use primarily two ways of storing potential energy: 1) as concentration gradients and 2) in molecules. A) Explain how energy can be stored in these two forms and how it can be used to do other work. B) Propose an analogy that can explain each of these forms of energy storage using everyday items.arrow_forwardEnzymes lower the activation energy, but where does the energy to lower the activation energy come from?arrow_forwardIn simple terms, what is ATPase?arrow_forward
- Explain the concept of activation energy and how it relates to enzymes' ability to do their jobs.arrow_forwardLook at the glycolysis pathway (Figure 22.3). With what type of reactions are kinase enzymes usually associated?arrow_forwardThe movement of energy between living organisms is a matter of atoms, molecules and compounds being built into larger molecules or being broke into smaller ones. Reviewing the two equations for energy transference, which one is building energy? 6CO2 + 6H2O + energy --------> C6H12O6 + 6O2 C6H12O6 + 6O2 ---------> 6CO2 + 6H2O + energyarrow_forward
- Where would you expect to find more mitochondria –in a skin cell or in a muscle cell? Justify your answer.arrow_forwardWhen you exercise, your muscles are using ATP to do the movements. Thus, the cell is doing cellular respiration in order to replace the ATP it has used. A) Draw a series of diagrams showing the energy transfers that occur during exercise (include: ATP, muscle, heat, cell respiration, glucose). B) When we exercise, we produce a lot of heat, to cool us down, our body produces sweat. According to the laws of thermodynamics, where is the heat coming from? C) When we exercise to lose weight, where is that mass going (do we sweat it out, it turns into heat, becomes digestive waste, how do we eliminate it?)?arrow_forwardCan you answer all the parts to following question, true or false: Q27: A: Because enzymes reduce the activation energy of a reaction the resulting free energy produced by the reaction is also reduced (True or False) B: Living things create energy through the breakdown of food into nutrients which the cell can use. (True or False) C: All tissues in the body are able to use ketone bodies to generate energy (True or False) D: Autophosphorylation is a mechanism of receptor activation for both Insulin and leptin (True or False)arrow_forward
