Dinitrophenol (DNP) is an ‘uncoupler' which causes membranes to become permeable to H+. Describe what would happen if DNP was added to plants which were carrying out photosynthesis.
In Madeleine L'Engle's children's novel A Wrinkle in Time, the mitochondria in one of the characters begins to die. Explain what would happen to people who lost their mitochondria, and describe why
A plasmid digest with BamHI generated 2 kb and 4 kb fragments. Digest of a plasmid with HindIII produced 6 kb fragment. Double digest with both enzymes produced 1 kb, 2 kb and 3 kb fragments. Sketch
Explain how would you build the cell (structure of the cell) and explain why would you build it that way (function of cell)? Explain how do you know the cell is alive?
Explain what kind of ER targeting signal sequences each of the given proteins would require for proper translation and localization:
Give a list explaining at least five similarities and three differences between plant and animal cells. In addition, select five internal structures of plant or animal cells (organelles) and explain
Bacterial cells are prokaryotic. Choose two structures of bacterial cells and in brief explain them; what do they look like, what are they composed of? Then, describe how these two structures permit
Then describe how these plant or animal cell structures or organelle function. Explain how do these functions support activities of the plant or animal cell and enable survival of the multicellular
Based on the latest publication of the Neandertal and Denisova genomes, explain the present model for putative hybridization and gene flow between these lineages and modern humans.
In a cell, there is less water on the inside and less glucose on the outside. Water wants to enter the cell and the cell wishes to transport in more glucose. Relative to the cell, what kind of envir
Describe the primary difference between passive and active transport in terms of concentration gradients?
A type of cell termed as a lymphocyte makes proteins which are exported from the cell. You can track the path of these proteins within the cell from production via export by labeling them with radio
I want to choose and describe two organelles and compare their structure and function. What would be a specific probable effect on the cell if each of the organelles were lost?
Describe the relation between muscles, ATP energy and the calcium ion. I will be using for class, if there are any references please comprise them.
Choose at least two cell organelles. What does each organelle do? What changes would occur in the cell if your first organelle took over all the duties of the second organelle?
What structure is found in the eukaryotic cell's nucleus and what is its equivalent in the prokaryotic cell? Write down the advantages of the three different types of vacuoles found in the eukaryotic
Prokaryotic cells are simple cells. Eukaryotic cells are more complex. What structures do eukaryotic cells have that prokaryotic cells do not? What are different kinds of eukaryotic cells? How do th
Eukaryotic cells are complicated in organization and structure, especially when you consider their small size. Consider the organelle contents of the typical eukaryotic cell.
The endosymibiotic theory recommends a description of the origin of mitochondria, chloroplasts and eukaryotic cells. Describe the evidence for this theory. Are you convinced?
Comprise any reactions needed for this process, and describe how the energy from the sun ends up as chemical energy for the anaerobic organism or cell.
Complete explanations of photosynthesis and aerobic respiration. Explain how these two processes are linked between plants and animals based on the reactants and products (water, carbon dioxide, glu
Some of the species of bacteria which live at the surface of sediment on the bottom of lakes are facultative anaerobes; which is, they are capable of either aerobic or anaerobic respiration.
The integrity of the plasma membrane is necessary for cellular survival. Could the immune system use this fact to destroy foreign cells which have invaded the body?
An integrin is an integral membrane protein in the plasma membrane of cells. This plays a role in the attachment of a cell to the extracellular matrix (ECM) and to other cells, and in signal transd
