Homework Answers
1. ATP synthesis occured due to chemiosmosis i.e movement of protons across the thylakoid membrane from a region of higher concentration to a region of lower concentration.
2. Cytokinesis in bacterial cells is completed by tubulin like protein called Ftsz so option c is correct .In eukaryotes cell plate formation followed by the involvement of tubulin to form the contractile ring occurs.

of the three types of fibers; microfilaments (or and intermediate filaments are fibers with diameters in a Microtubules are the filaments) are the middle range. Microtubules are hollow rods about 25 nm in diameter and 200 nm to 25 um in length. Microtubule fibers are constructed of the globular protein A tubulin dimer consists of two slightly different polypeptides: a-tubulin and B-tubulin. Microtubules shape and support the cell and serve as tracks to guide motor proteins carrving organelles to their...

Question 26 (1 point) How is cytokinesis in plant cells different from cytokinesis in animal cells? Cytokinesis in plant cells requires formation of a cell plate; cytokinesis in animal cells requires formation of a ring of actin. Cytokinesis in plant cells occurs during G2; cytokinesis in animal cells occurs in the M phase of the cell cycle. Cytokinesis in plant cell results in one large cell with two nuclei; cytokinesis in animal cells results in two cells, each with one...
