I'm sorry, you want too much Tags: entrance entrance summary of biological knowledge of biological education entrance biological questions
1. The following eukaryotic cell structures and components, corresponding wrong is A. Membrane: lipids, proteins, carbohydrates B. Chromosome: mrsa RNA, protein C. Ribosome: protein, RNA D. cytoskeleton: proteins [answer] B [A] is the main component mrsa of the cell membrane lipids, proteins and small amounts of carbohydrates, A correct; chromosome consists of DNA (DNA) and proteins, B error; ribosomal protein and RNA (rRNA) constitutes, C correct; cytoskeletal microtubules and actin filaments are formed by the protein composition, D is correct. [Evaluation] This title examines questions memorizing ability, students mrsa examine the structure and composition of the eukaryotic cell to understand the relevant knowledge, is not difficult. 2, some of the eukaryotic cells have significantly mrsa increased membrane area is conducive to improve the adhesion of the enzyme structure metabolic efficiency. The following does not belong to such a structure is () A. B. dendrites of nerve cells mitochondria cristae C. endoplasmic reticulum D. thyroid mrsa cells chloroplast grana [answer] A [A] expanded the nerve cell dendrites surface area, and is conducive to receive stimulation impulses incoming cell body, A does not belong to a structure improved metabolic efficiency; folded into the mitochondrial cristae, increased membrane area, and provide attachment sites for the enzymes relating to the aerobic respiration. The rough endoplasmic reticulum thyroid cells attached mrsa to the enzyme structure. Chloroplast thylakoid stacked to form grana, there are enzymes involved in photosynthesis, the B, C, D belongs to improve metabolic efficiency mrsa of the structure. [Question] This title examines the significance evaluation eukaryotic cell membrane, intended examinee memorizing and understanding. 3 biofilm eukaryotic cells into separate compartments so that the cell can be a variety of chemical reactions simultaneously, without mrsa interfering with each other. The following description is correct A. Nuclear mRNA synthesis and processing is the place B. Golgi peptide chain synthesis and processing establishments C. The mitochondrial oxidation of glucose is decomposed mrsa into CO2 and H2O D. Synthesis and secretion of a variety of lysosomal acid hydrolases [answer] A [A] nucleus is transcribed places, so is the place mRNA synthesis and processing, A correct; ribosomal peptide chain synthesis sites, B error; glucose can not into the mitochondria, C error; lysosomal enzymes are synthesized on ribosomes by the endoplasmic reticulum and Golgi processing and modification, D errors. [Review] The main question mrsa papers examine the structure of cells, but involved a wider knowledge, more integrated, moderate difficulty.
