Cellular respiration is a process that produces usable energy for cells in the form of adenosine triphosphate. The presence or absence of oxygen determines the metabolic pathway that a cell undergoes for producing adenosine triphosphate. Explain the evolutionary advantages for eukaryotic cells when it comes to the metabolic pathway

When making bread with common yeast, the reaction starts as an aerobic process and then becomes an anaerobic process after the oxygen is spent. A baker has created a new strain of yeast which contains no cytochrome c gene and, thus, no cytochrome c protein. This will affect what the yeast strain can do to obtain energy.  Use the passage to answer the question. Since the air bubbles in bread are generated by yeast, how will the spaces in this bread compare to those in a loaf made using normal yeast?   A. more bubbles    B. differently-shaped bubbles   C. smaller bubbles   D. bubbles more on the interior of the loaf

Consider a triglyceride molecule (dietary fat) and it’s components. If a cell uses a triglyceride molecule as an energy source, at which processes (stages) of cell respiration do the components enter cell respiration?   3.Which phosphate bond in ATP is broken or made to release or contain energy? 4.Cellular respiration in eukaryotic cells is aerobic. Briefly define the term aerobic. 5.Consider question #4above. Briefly describethe role or function of oxygen in cellular respiration? 6.At which stage is the greatest amount of carbon dioxide released? 7.What is the function of the molecule NADHand FADH2? 8.What is the role of protons (hydrogen ions)in the electron transport chain. 9.Briefly describe the function of ATP synthase. 10.Briefly describe the mechanism of action for the poison cyanide.

explain why the statement is correct. Within the eukaryotic cell, most of the energy stored in ATP is produced through the: mitochondrion completing the oxidation of pyruvate (3 carbon chains)

During aerobic respiration in the mitochondria of eukaryotes, which substrate molecules provide the oxygen atoms that end up in product water molecules? C6H12O6, H2O, and O2 only H2O and C6H12O6 only C6H12O6 and O2 only H2O only O2 only

In living cells, true equilibrium is dangerous because if the rate of a forward reaction is equal to the rate of the reverse reaction, a wasteful cycle is produced during which the cell gains no new nutrients.  In this situation, the cell will eventually die.  Therefore, organisms have many ways of ensuring that reactions move only in the forward direction.  One of these means is control over reactant concentration. The Citric Acid Cycle is a series of reactions that occur in eukaryotic cell mitochondria which are essential for providing energy to living cells.  During one of these reactions, a molecule known as oxaloacetate is combined with acetyl coenzyme-A to produce citrate.  Normally, the concentration of oxaloacetate in mitochondria is very low.  If the cell is in need of more energy and the concentration of oxaloacetate increases, what will happen to the direction and of this reaction?  How do you suppose this affects the overall amount of energy product produced?

Which of the following would take place in the cytosol of a eukaryotic cell? Select all that apply. Chemiosmosis Citric Acid Cycle Electron Transport Chain Glycolysis Pyruvate Oxidation

An anaerobic prokaryotic cell is able to generate a maximum of how many molecules of ATP from the catabolism of one glucose molecule into two molecules of ethanol? 2 molecules of ATP 4 molecules of ATP 6 molecules of ATP 30 molecules of ATP 32 molecules of ATP

A complex enzyme that can synthesize ATP, and is often called ATP synthase, is found in both mitochondria and chloroplasts.       True   False
