C4 plants differ from C3 plants in that they do what?

What structure allows for the passage of materials between adjacent animal cells through pores in the cell membrane?

The reactants of a chemical reaction have a total energy of 182 kJ/mol while the products have a total energy of 43 kJ/mol. What is the overall energy of the reaction? Include units. [freeenergy] Is this reaction exergonic or endergonic?  [reactiontype] Will this reaction occur spontaneously? Yes or no. [spontaneity] 

ATP synthase adds phosphate groups to ADP molecules in a process that is fueled by chemiosmosis. The proton gradient for this process is produced by a number of redox reactions, ending in the production of water from oxygen gas. This is an example of what type of phosphorylation?

In the citric acid cycle, succinyl-CoA synthetase removes coenzyme A from succinyl-CoA. In the process, a phosphate group is added to the intermediate and is ultimately transferred to a ADP molecule, producing ATP as a by-product. This is an example of what type of phosphorylation?

Which of the following is true of cyclic electron flow within the photosystems? Choose all that apply.

Which of the following utilizes oxidative phosphorylation? Choose all that apply.

The reactants of a chemical reaction have a total energy of 262 kJ/mol while the products have a total energy of 172 kJ/mol. What is the overall energy of the reaction? Include units. [freeenergy] Is this reaction exergonic or endergonic?  [reactiontype] Will this reaction occur spontaneously? Yes or no. [spontaneity] 

What structure binds animal cells tightly together into a waterproof layer of tissue?

Which of the following is the first stage of cellular respiration to produce carbon dioxide?
