The loss of electrons is called? In a redox reaction what agent is the electron donor and electron acceptor? Reduction Glucose is oxidized, oxygen is reduced, and what happends to the potential energy of the electrons?

Why does the rich reservoir of electrons in a cell not spontaneously combine with O2? They lack the activation energy.

What lowers the barrier of activation energy, allowing fuels to be oxidized slowly? Does cellular respiration oxidize glucose in a single step? Glucose and other fuels are broken down gradually in a series of steps, each catalyzed by a specific enzyme Dehydrogenase enzymes do what?

Strip two hydrogen atoms from the fuel e. When is energy is tapped to synthesize ATP? Cellular respiration uses an electron transport chain to.? Break the fall of electrons to O2 into several steps.

Respiration occurs in three metabolic stages: Glycolysis Which takes place within the mitochondrial matrix, completes the job by composing a deribative of pyruvate to carbon dioxide? Yes The energy released at each step of the chain is sotred in a form the mitochondrion can use to make ATP.

This mode of ATP synthesis is called? Oxidtaive phosphorylation accounts for what percent of ATP generated by repiration? What is substrate-level phosphorylation? How does glycolysis harvest chemical energy? It begins catabolism by breaking glucose into two molecules of pyruvate.

In cellular respiration, carbohydrates and other metabolites are oxidized, and the resulting energy-transfer reactions support the synthesis of ATP. Inspiration (the process of inhaling) begins as the external intercostals and diaphragm contract. When this happens, the lungs expand.

After this, negative pressure is used to facilitate respiration. So, air moves from an area of higher pressure, which is the air, to an area of lower pressure in the lungs and aveoli.

Determine the optimum temperature for respiration in yeast. describe in detail one way of: measuring the rate of transpiration measuring the rate of photosynthesis separating pigments () Describe the similarities and differences between the biochemical pathways of aerobic respiration and photosynthesis in eukaryotic cells.

PHOTOSYNTHESIS, RESPIRATION, PRODUCTIVITY of an ECOSYSTEM, ENERGY TRANSFER #11 # Photosynthesis and cellular respiration recycle oxygen in ecosystems. Respond to TWO (and only two) of the following: a. Explain how the metabolic processes of cellular respiration and photosynthesis recycle oxygen.

b. Breanna Takacs AP Biology A2 11/27/12 Cellular Respiration Free Response Questions The Krebs Cycle and oxidative phosphorylation are both processes involved in obtaining ATP from pyruvate, the end product of glycolysis.
