Exam 6: Photo Synthesis and Cellular Respiration

In warm and dry conditions,when CO₂ levels fall and O₂ levels rise,photorespiration occurs as a result of plants closing their ________.

The three stages of aerobic catabolism are

If plants are able to capture energy from the sun,why do they need to pass that energy through the chemical reactions that are necessary to produce ATP?

The molecular energy carrier that has less energy than other energy carriers but is more versatile because of its ability to be used in a larger variety of chemical reactions is ________.

Which of the following molecules carries electrons that will be used to reduce other molecules in an electron transport chain?

What is the role of water in photosynthesis?

Most people respond to a prolonged stay at high altitude by producing more hemoglobin,producing more and larger red blood cells,or both.

Which of the following statements describes the function of the electron transport chain (ETC)in photosynthesis?

The process that converts NADH into NAD⁺ to keep glycolysis running under anaerobic conditions is called ________.

In C₄ plants,carbon fixation and the workings of rubisco are spatially separated.Carbon fixation occurs in the ________ cells,and then rubisco adds CO₂ to RuBP in ________ cells.

You have shrunk to molecular size and find yourself in a mitochondrial chamber where protons are being pumped out of the chamber and across a membrane into another chamber.You are in the mitochondrion's ________.

The number and arrangement of membranes inside a chloroplast are important to the chloroplast's functions.How would the absence of these membranes affect the manufacture of ATP in a chloroplast?

Most of the oxidation reactions that produce NADH in a cell take place in

During the process of photosynthesis,plants capture the kinetic energy of moving photons and transform it into potential energy in the form of

Stomata admit CO₂ to the leaf interior but also facilitate the loss of water from the leaves; plants must regulate their stomata carefully or risk dehydration.A reasonable hypothesis associated with the global increase in atmospheric CO₂ is that plants will

The most common cause of death by poisoning around the world is ________.

NADH serves as an energy carrier in living organisms by coupling ________ with ________.

The green pigment that is most commonly associated with photosynthesis is ________.

Biologists believe that Earth's early life-forms were exposed to an atmosphere that had no molecular oxygen and therefore had not yet evolved the Krebs cycle.If so,alcoholic fermentation would have been particularly critical to life,because without this pathway

Several plant pigments have significant antioxidant qualities and can protect a cell from the damage inflicted on its biomolecules by free radicals.
