A shortage of available ATP would hinder a cell's ability to import Select one: a. water. b. oxygen. c. protein. d. carbon dioxide.

Your science teacher says that matter is conserved in the process of cellular respiration.  What does he mean by that? (a) None of the atoms in the food that we eat are destroyed during the process, and no new atoms are created in the formation of carbon dioxide, water and ATP (b) None of the molecules in the food are destroyed during the process, and no new molecules are created after the reaction between glucose and oxygen (c) Molecules in our food are destroyed, and new molecules, of carbon dioxide, water and ATP are created (d) None of the matter, whether solid, liquid, or gas, changes states during the process.

What cellular organelle is the final destination of oxygen? A. Left B. Middle C. Right D. Nucleus E. Plasma Membrane F. Golgi G. Mitochondrion H .Endoplasmic Reticulum

Which transporter is typical of inner membrane of mitochondrial membrane? A. Pyruvate transporter B. H+ -ATPase C. Amino acid transporter D. Sugar transporter E. Lipid transporters

The proteins : oxidase ,kinase,lipase, isomerase are all known to function as  a. channels b. transporters c.receptors d. enzymes e. none of the above

Select the correct pairing of a structure and the process it is associated with.    A. Schwann cells……..muscle contraction  B. ATP synthase…..electron transport chain  C. H+ pump……facilitated diffusion  D. Mitochondria…..protein synthesis

Model 1 and Model two are diagrams showing the process of two types of bulk transport which require energy. Which of the following statements correctly describes the type of transport that is occurring in Model 1 and Model 2? A . Model 1 and 2 are types of passive transport. B . Model 1 and 2 help to transport only one molecule at time. C . Model 1 shows endocytosis, where the cell surrounds molecules from outside the cell and takes the molecules into the cell. D . Model 2 shows endocytosis, where the cell surrounds molecules from inside the cell and releases them outside of the cell.

Which of the following glycoproteins compose the ECM? Select one: a. fibronectin b. All of the answers are correct. c. elastin d. collagen

When cellular transport through the plasma membrane must be provided with energy in form of ATP to power the transport process, what is this called?   A. Selective permeability     B. Passive transport   C. Active transport   D. Diffusion

The cardiovascular, respiratory, and gastrointestinal systems all worktogether to ensure that cells of the human body are able to carry out vitalreactions including aerobic respiration and protein synthesis. Write a short account to explain how each of these three systems ensure that cells receive the required raw ingredients needed for such cellular reactions, and how two of the systems contribute to the removal of thewaste products created.  You must focus on how these three systems are adapted and inter-related to ensure that the molecules required for aerobic respiration and protein synthesis are made accessible to body cells where these cellular reactions take place. In addition, you should consider how two of these systems work together to remove waste products that are formed during cellular reactions from cells to be excreted. All three systems must be considered, and you should include specificdetail such as the role of named enzymes in the gastrointestinal tract, and named…
