Question

True or False (1 points X 10-10 points) 21 Tight junctions and desmosomes are terms that refer to the same structure. In eukaryotic cells, DNA is only found in nucleus. 23 Cell-cell anchoring junctions are always connected to intermediate filaments. 24 During photosynthesis, oxygen molecules are generated in photosynthesis I. The formation of ATP in the mitochondria and chloroplast both involve the formation of a proton gradient. 25 26 The protein synthesis does not always start in cytoplasm. 27 Clathrin coated vesicles transport material endosome to lysosome. Cop I is found in the vesicles transporting between ER and Golgi apparatus 28 29 The general name for an enzyme that adds phosphate to a protein is phosphatase 30 Nerve and muscle cells are in G1 phase.

Explanation / Answer

21) False because tight junctions are occulding junction while desmosomes are anchoring junctions

22) False because it is also found in mitochondria and chloroplast

23) True

24) false.oxygen molecule is generated by photosystem II

25) True

26) false because translation takes place in cytoplasm as ribosomes are present in cytoplasm

27) true

28) false as cop II is involved transport from ER to Golgi while COP I is involved in reterograde that is from golgi to ER.

29) False as it removes phosphate group

30) false they are in G0 phase
