In plant cells, H+ pumps maintain a low concentration of H+ inside the cell. As long as a low H+ concentration is maintained inside the cell, H+ -driven symporters on plant cell membranes can use the electrochemical gradient of H+ to:

The “hydrophobic effect” is the driving force of the spontaneous assembly of the lipid bilayer of cell membranes in water. What does that mean?

What is a TRUE statement about how cholesterol influences the lipid bilayer?

Which proteins pictured below are peripheral membrane proteins?  

A scientist studying the impact of the histone code on cancer adds a drug that BLOCKS histone acetyl-transferase (HAT) function in a breast cancer cell culture. What do you predict will happen to the cells?

How does the protein Adaptin contribute to clathrin-mediated endocytosis?

What is TRUE about the synthesis of carbohydrates vs. the synthesis of proteins, DNA, and RNA?

You are a molecular biologist studying how the membrane receptor FGFR1 influences heart development in chickens. You prepare a set of slides with sections of embryonic chicken heart cells for indirect immunoflourescence to examine the distribution of FGFR1 in these cells. Which combination of antibodies should you use for this experiment?

Membrane fusion between a vesicle and the plasma membrane is mediated by vSNARE/tSNARE binding. TRUE or FALSE:  This involves a stage in which a temporary lipid bilayer is formed between the original leaflet closest to the vesicle lumen and the original leaflet closest to the extracellular space (the area outside of the cell). 

TRUE or FALSE: Tertiary protein structure depends on interactions involving the R groups of amino acids, while secondary protein structure does not.
