下面为大家总结的是以字母E开头的SAT2生物专业词汇的相关内容，后面附有汉语翻译和英语解析。SAT2生物考试对词汇量的要求是比较大的，尤其是对于这些比较关键性的专业词汇，对大家理解题意有非常大的影响。下面我们来看看详细内容吧。

　　Ear(耳)

　　Sensory organ capable of detecting sound.

　　ecological succession(生态序列)

　　The progression of plant life and attendant animal life in a given geographic location, from pioneer plant to climax community.

　　Ecology(生态学)

　　The study of the interactions and relationships of populations with each other and their abiotic environments.

　　Ecosystem(生态系统)

　　A community of organisms and its abiotic environment.

　　Ectotherm(变温动物)

　　See cold-blooded.

　　Egg(卵)

　　The female gamete in sexual reproduction; also called an ovum.

　　electron microscope(电子显微镜)

　　An instrument that uses an electron beam to form clear and highly magnified images of microscopic structures. Electron microscopes cannot take pictures of living organisms.

　　electron transport chain(电子传递链)

　　The final stage of aerobic respiration. The electron transport chain establishes an electrochemical gradient across the inner mitochondrial membrane that powers the synthesis of ATP in oxidative phosphorylation.

　　Embryo(胚胎)

　　Before birth, the maturing cells that will grow into a fully formed organism.

　　endocrine system(内分泌系统)

　　Control system of the body that functions by releasing hormones into the bloodstream.

　　Endocytosis(内吞作用)

　　Process by which liquids or small solid particles are taken into a cell in the form of small vesicles that are produced through the invagination of the cell membrane.

　　endoplasmic reticulum(ER/内质网)

　　A network of membrane-bound tubes and sacs in the cytoplasm. The endoplasmic reticulum is a major site of protein and lipid synthesis.

　　Endoskeleton(内骨)

　　An interior skeleton found in vertebrates made of bone and cartilage.

　　Endotherm(恒温动物)

　　See warm-blooded.

　　energy pyramid(能级图)

　　Energy in a community can be depicted as a pyramid of food or biomass. The availability of food, biomass, and energy from the trophic level of producers up through each subsequent level on the food web is approximately 10 percent of that available in the previous trophic level.

　　Enzymes(酶)

　　Biological catalysts made from proteins. Enzymes have attachment locations for substrates called active sites.

　　Estrogen(雌激素)

　　Hormone that stimulates the growth of the uterine lining during pregnancy and that develops and maintains the female secondary sex characteristics, such as the development of mammary glands, a narrower waist and wider hips, axillary and pubic hair, and a higher-pitched voice.

　　Eukaryote(真核生物)

　　An organism whose cells have membrane-bound intracellular organelles, including a nucleus containing multiple chromosomes. Eukaryotes, unlike prokaryotes, can undergo sexual reproduction via meiosis. Compared to prokaryotes, eukaryotes are more complex and arose later in evolutionary history. Protists, fungi, plants, and animals are all eukaryotic organisms.

　　excretory system(排泄系统)

　　The organ system that filters blood and removes nitrogenous wastes from the body in the form of urea or uric acid. In humans, the two kidneys are the vital organs of blood filtration. In annelids, nephridia fill the filtering role; Malpighian tubules do the same in arthropods. In humans, other important structures of the system are the ureters, the urinary bladder, and the urethra.

　　Exocytosis(外排作用)

　　Process by which molecules are secreted from the cell. Exocytosis occurs when a vesicle fuses with the cell membrane and releases its contents to the outside.

　　exoskeleton (外骨)

　　A rigid, chitinous protective structure that surrounds the bodies of arthropods and provides support.

　　Eye(眼睛)

　　Sensory organ capable of detecting light.

　　以上就是关于SAT2生物专业词汇的全部内容，是以字母E开头的。大家可以在备考自己的SAT2生物考试的时候，对此加以适当的参考和借鉴，以便在考试的时候，可以更加的顺利，更加的轻松。
