Question

13. Cells are anchored within the extracellular matrix in tissues. Extracellular matriox collagen, are synthesized within cells and secreted to the extracellular space. Select the option that proteins, such as correctly identifies the path taken by collagen from when it is synthesized on ribosomes to its release from cells.

A) primary B) secondary C) tertiany D) quaternary E) all of the above 16. Which of the following has the most glycosidic bonds? A) Glucose B) Sucrose C) Fructose D) Glycogen E) Galactose 17. In a chemical reaction, the standard free energy change (AG") is calculated to be 3.67 callmol. What can be said of the chemical reaction? A) The reaction is at equilibrium under standard conditions. B) The reaction goes spontaneously to the right under standard conditions. C) The reaction is not spontaneous under standard conditions. D) Products predominate over reactants at equilibrium under standard conditions. E) There can be no reaction. 18. Starting with shredded spinach leaves, you follow a procedure that allows for separation of cellular organelles. You are specifically looking for the fraction that contains chloroplasts. To identify this fraction, you should test for the A) phospholipids unique to intracellular membranes. B) general presence of enzymes that fix carbon dioxide. C) phospholipids unique to the mitochondrial membrane. D) polysaccharides that specifically surround the mitochondria. E) presence of enzymes associated with cellular respiration.

Explanation / Answer

13) correct answer is (c) the collagen formed by ribosome his from rough ER to Golgi apparatus through transport vesicles and then secreted through plasma membrane.

14)The oxidative phosphorylation forms 34 ATP .So the correct answer here is (e).

15) covalent bonds are important for stabilising the primary structure of protein
