In aerobic respiration, chemiosmotic generation of ATP is driven by: a. P_ trans

Question

In aerobic respiration, chemiosmotic generation of ATP is driven by: a. P_ transfer through the plasma membrane. b. the Na^+/K^+ pump. c. a difference in H^+ concentration on the two sides of the inner mitochondrial membrane. d. osmosis macromolecules. e. large quantities of ADP How and where is ATP made in a eukaryotic cell? a. ATP is only made in the mitochondria in response to chemiosmosis b. ATP is made in all compartments of the cell in response to endergonic reactions and used to drive exergonic reactions in the cell. c. ATP can be made by direct phosphorylation of ADP in the cytoplasm, and by complex that uses the energy from a proton gradient to drive ATP synthesis in the mitochondria. It also be made in other locations in the cell, depending on the cell type. d. ATP can be made by an enzyme complex that uses the energy of protons moving down their concentration gradient from the mitochondrial matrix to the cytoplasm to make the ATP What happens to the oxygen that is used in cellular respiration? a. It is converted to carbon dioxide b. It is used to make glucose c. It is used to make Krebs cycle intermediates d. It is reduced to form water e. It is converted to acetyl-CoA Glucose is not our only food source, nor the only one we can utilize in our bodies to generate energy. Other primary sources of energy include other sugars, proteins, and fats. What metabolic intermediate are fats primarily converted into? a. Pyruvate b. Acetyl-CoA c. Krebs cycle intermediates d. Electron transport chain components e. ATP Synthase Where do the carbon atoms in glucose come from? a. Sunlight b. Carbon dioxide c. Water d. NADPHI In photosynthesis takes place inside the ____. a. chloroplasts b. mitochondria c. cytoplasm d. Golgi apparatus in photosynthesis, carbon fixation occurs: a. in photosystem I b. in the electron transport chain c. in photosystem II d. in the Calvin cycle e. during photorespiration
