The anaerobic, chemoautotrophic archaeobacterium Methanococcus jannaschii uses which of the following carbon-fixation pathways to obtain organic carbon from CO2? cell bio  the Hill reaction the Wood-Ljungdahl pathway the Calvin cycle oxygenic photosynthesis the Krebs cycle

A student lists some characteristics of anaerobic respiration. 1. It produces 36 molecules of ATP. 2. It uses oxygen to produce energy. 3. It occurs in the cytoplasm of the cell. 4. It results in the production of lactic acid. Which characteristics did the student list incorrectly? Characteristics 2 and 3 are incorrect because anaerobic respiration produces energy without oxygen and occurs in the mitochondria of a cell. Characteristics 1 and 4 are incorrect because anaerobic respiration produces 2 molecules of ATP and does not produce lactic acid. Characteristics 3 and 4 are incorrect because anaerobic respiration occurs in the mitochondria of a cell and does not produce lactic acid. O Characteristics 1 and 2 are incorrect because anaerobic respiration produces 2 molecules of ATP and produces energy without oxygen.

Which of the following membranes or compartments can be found in both a cyanobacterial cell and a typical photosynthetic eukaryotic cell? the inner nuclear membrane the outer mitochondrial membrane the mitochondrial matrix the inner mitochondrial membrane the thylakoid membrane

The Calvin cycle reactions are sometimes called the “lightindependent reactions” or “dark reactions” to contrast them with the light (or light-dependent) reactions. Can the Calvin cycle be sustained in algae that are kept in total darkness for several days? Why or why not

Which statement best describes translation? 00 The process converts an mRNA sequence into a polypeptide. It uses ribosomes to make mRNA. It produces Okazaki fragments. It produces RNA from DNA molecules The process breaks bonds between amino acids.

In anaerobic respiration, what will happen if a bacterium uses nitrates as the terminal electron acceptors? nitrogenlaxation nitrification denitrification both nitrogen fixation and nitrification
