S Metabolic Processes Test

• Chemical potential is the energy is stored in foods that we consume
• An active cell that requires large amounts of energy will have many mitochondria
• G3P is a common molecule in cells. In CR, it is a product of glucose catabolism during glycolysis. It is also produced as a result of the catabolism of glycerol
• NADH and FADH2 carry electrons to the electron transport chain (ETC)
• The Krebs cycle occurs inside the matrix of the mitochondrion
• In the Krebs cycle, NADH and FADH2 are formed from G3P
• The ETC is located on the inner membrane of the mitochondrion
• Blue light has more energy and a shorter wavelength than red light
• If an enzyme is regulated by competitive inhibition, the substrate competes with the inhibitor for the active site
• Cyclic electron flow limits the formation of NADHP
• ATP and NADPH are components of the Calvin cycle that are provided by LDR reactions from photosynthesis
• Photosystem II uses water as its source of electrons to reduce PQ
• NADPH is used to convert CO2 into organic molecules during the Calvin cycle
• Glycolysis is common to both aerobic cellular respiration and fermentation
• In glycolysis, glucose is converted into pyruvate
• how many molecules of ATP and NADPH are used to synthesize one molecule of glucose during photosynthesis?

  12 ATP and 18 NADPH
• A type integral membrane protein that causes tjr electron gradient required for chemiosmosis

  Proton Pump
• the addition of a phosphate group to adenosine diphosphate (ADP) through an enzymatic reaction?

  Substrate level Phosphorylation
• Which stage of cellular respiration does not produce any CO2?

  Glycolysis
• Reducing agent is not a term that can be used to describe NAD+
• The mitochondrial matrix is relatively basic due to the protons having been pumped out
• Cellular respiration that occurs in the absence of oxygen?

  fermentation
• Enzyme that C4 plants contain but which C3 plants do not?

  PEP Carboxylase
• The use of light energy to split a molecule of water?

  Photolysis
• The form of membrane transport used by the proton pumps in the ETC?

  Active transport
• The stage of photosynthesis in which oxygen is released?

  Light reactions
• Enzyme used to fix carbon in the calvin cycle?

  Rubisco
• The fixation of oxygen instead of carbon dioxide in photosynthesis?

  photorespiration
• electron carrier used in CR but not phtotsynthesis?

  FADH2
• Metabolic process used to create glucose in very hot environments?

  C4 Photosynthesis
• The form of membrane transport used by ATP synthase to make ATP?

  Facilitated Diffusion
