Why does a muscle cell contain many mitochondria and a white blood cell contain many lysomes?
If you have one group of kids in Denver [group A] (lower pressure, lower temperatures) and another group of kids in New Orleans [group B] (higher pressure, higher temperatures) and they performed an aerobic respiration in a lentils experiment, how could their results be made similar or comparable?
What would be the effect on the size of a cell membrane when the secretory pathway is active? Will this cause a problem for the cell, and what might a cell do to keep this from becoming a problem?
What is the difference between passive and active transport? This job gives the definitions of each, including the 3 types of passive transport.
What does the process of chemiosmoisis in the chloroplast involve? What about the process of mitochondrion? These areas are included.
Autoradiography depends upon particles emitted from radioactive atoms striking a photographic emulsion that lies on top of the tissue section. When the emulsion is developed, the site where the particle struck the emulsion is developed, the site where the particle struck the emulsion appears as a silver grain, as in figure 8.3a.
Myosin action differs from that of kinesin in that one of the kinesin heads is always in contact with a microtubule, whereas both myosin heads become completely detached from the actin filament. How are these differences correlated with the two types of motor activities in which these proteins engage?
List three things you could do that would shift the dynamic equilibrium of an in vitro preparation of tubulin and microtubules toward the formation of microtubules. List three treatments that would shift the equilibrium in the opposite direction.
What is a pulse chase?
