Water by one degree celsius iv kilocalorie (kcal or cal) = amount of heat required to raise the temperature of one kilogram of water by one degree celsius (1000 cal) v temperature = measure of heat intensity due to the average kinetic energy of molecules in the body of matter. The first of these is the kinetic energy of the molecule, which is most frequently measured as the temperature of the system we will write a custom essay sample on ap biology lab 1 report specifically for you the cell can burst, which kills the cell so cells usually have some kind of mechanism for preventing too much water from. The first of these is the kinetic energy of the molecule, which is most frequently measured as the temperature of the system the size of the molecule also affects how rapidly it will diffuse diffusion can occur through a cell membrane. As the temperature increases, the enzyme and substrates have more kinetic energy thus, it will increase the chance of successful collisions occur as there is a higher chance that the enzyme and substrate both have the sufficient activation energy for the reaction to occur.

To learn about the different types of energy and how they relate to metabolism for each of the questions, we researched th e answers from reliable sources the 1st law of thermodynamics is that energy cannot be created or destroyed and that it either transfers or transforms into a different state of energy. Investigation 4 diffusion and osmosis 4 procedure 2: modeling osmosis and diffusion (adapted from pages 1-4 of advanced placement biology student laboratory manual c2001) in this experiment, you will create models of living cells using dialysis tubing.

Introduction: cells have kinetic energy and it causes the molecules of the cell to move around and bump into each other diffusion is one result of this molecular movement diffusion is the passive movement of molecules from an area of higher concentration to lower concentration. To solve this problem, paramecium cells have a specialized organelle, the contractile vacuole, which functions as a bilge pump to force water out of the cell the cells of plants, prokaryotes, fungi, and some protists have walls that contribute to the cell’s water balance.
