FGCU BIO Unit 2 Exam Questions and Answers New (2025/2026) Solved 100% Correct

Cells of the small intestine will incorporate radioactively labeled amino acids into proteins. This "tagging" of newly synthesized proteins enables a researcher to track their location. In this case, we are tracking an enzyme secreted by intestinal cells. What is its most likely pathway? - ️️ER → Golgi → vesicles that fuse with plasma membrane which of the following processes is endergonic - ️️the synthesis of glucose from carbon dioxide and water Which statement correctly characterizes ER-bound ribosomes? - ️️Bound ribosomes generally synthesize membrane proteins and secretory proteins. Which structure is common to plant and animal cells? - ️️mitochondrion Cyanide binds with at least one molecule involved in producing ATP. If a cell is exposed to cyanide, most of the cyanide would likely be found within the - ️️mitochondria. A primary objective of cell fractionation is to - ️️separate the major organelles so that their particular functions can be determined. In what ways do prokaryotic cells differ from eukaryotic cells? What structures are common to both? - ️️Prokaryotic: before nucleus vs. E: "true" nucleus no membrane bound vs. membrane-bound organelles; circular vs. nucleus/organelles DNA vs. linear DNA According to the fluid mosaic model of membrane structure, proteins of the membrane are mostly - ️️embedded in a lipid bilayer. Which of the following factors would tend to increase membrane fluidity? - ️️a greater proportion of unsaturated phospholipids Which of the following processes includes all others? - ️️passive transport Some bacteria are metabolically active in hot springs because - ️️their enzymes have high optimal temperatures. Which of the following metabolic processes can occur without a net influx of energy from some other process? - ️️C6H12O6 + 6O2 CO2 + 6H2OIf an enzyme solution is saturated with substrate, the most effective way to obtain a faster yield of products is to - ️️add more of the enzyme. Which of the following is an example of potential rather than kinetic energy? - ️️a food molecule made up of energy-rich macromolecules What is the reducing agent in the following reaction? - ️️NADH The immediate energy source that drives ATP synthesis by ATP synthase during oxidative phosphorylation is - ️️the H+ concentration gradient across the inner mitochondrial membrane
