| 영문 | male reproductive system | 한글 | 남성생식기계 |
|---|---|---|---|
| 설명 | 남성의 생식기는 여러 기관으로 구성되어 있다. 고환, 부고환, 정관, 정낭, 전립샘, 외부성기(음경) 등으로 구성되는데, 실제적으로 정자를 생성하는 곳은 단 한 곳 고환뿐이며, 나머지 기관은 이를 돕는 기능을 수행하고 있다. 정자는 고환의 정세관이란 곳에서 만들어진 뒤에 밖으로 나와 긴 여정을 시작하게 된다. 그 뒤 부고환을 지나 좀 더 성숙해 진 뒤에 정관에서 정낭의 분비물과 만나고 다시 요도로 나가게 된다. 이때 요도 뒤쪽에 위치하는 전립샘의 분비물이 합쳐지게 되고 이 정액은 외부성기를 거쳐서 밖으로 나가게 된다.  |

| 영문 | urinary system | 한글 | 비뇨기계통 |
|---|---|---|---|
| 설명 | 비뇨기계통이라하면 콩팥으로부터 시작해서 요관, 방광, 요도에 이르는 일련의 오줌생성 및 저장, 배설기관을 일컫는다. 콩팥은 길이 약 2.5cm, 폭 약 5.1cm, 두께 약 2.5cm, 무게 약 120~160gm으로서, 내측에 콩팥문이 있어 혈관, 신경, 요관이 출입하고 있다. 콩팥은 속질과 겉질로 이루어져 있으며 수질은 10~15개의 추체(오줌을 모으는 역할)를 형성하고 겉질은 약 100만개의 콩팥단위으로 구성되어 있다. 요세관은 토리쪽뇨세관, 헨레고리, 먼쪽뇨세관, 집합관으로 형성되어 있으며, 추체와 술잔, 깔때기를 거쳐 요관으로 연결된다. 콩팥은 혈액을 여과하여 신체 신진대사의 최종산물을 오줌의 형태로 배설하며, 세포외액(extracellular fluid)의 전해질농도를 조절한다. 콩팥에서 형성된 오줌는 요관을 거쳐 방광에서 저장되고 있다가 적당한 시기가 되면 요도를 통해 외계로 배출된다. |

| ATP-dependent DNA strand transferase | <enzyme> From human cell nuclei; catalyses strand exchange between homologous DNA sequences; magnesium dependent, requires ATP hydrolysis Registry number: EC 2.7.7.- Synonym: ATP-dep-DNA-str trnsfase (26 Jun 1999) |
|---|---|
| ATP-diphosphatase | <enzyme> An enzyme that catalyses breakdown of ATP to AMP, usually extracted from plants, but aortic and placental forms have also been described. (18 Nov 1997) |
| ATP-monophosphatase | <enzyme> A group of enzymes which catalyze the hydrolysis of ATP coupled with another function such as transporting calcium across a membrane. These enzymes may be dependent on calcium, magnesium, anions, h+, or DNA. Chemical name: ATP phosphohydrolase Registry number: EC 3.6.1.3 (12 Dec 1998) |
| ATP phosphoribosyltransferase | <enzyme> An enzyme that catalyses the first step of the pathway for histidine biosynthesis in salmonella typhimurium. ATP reacts reversibly with 5-phosphoribosyl-1-pyrophosphate to yield n-1-(5'-phosphoribosyl)-ATP and pyrophosphate. Chemical name: 1-(5-Phospho-D-ribosyl)-ATP:pyrophosphate phospho-alpha-D- ribosyltransferase Registry number: EC 2.4.2.17 (12 Dec 1998) |
| ATP sulfurylase | <enzyme> An enzyme that catalyses the activation of sulfate ions by ATP to form adenosine-5'-phosphosulfate and pyrophosphate. This reaction constitutes the first enzymatic step in sulfate utilization following the uptake of sulfate. Chemical name: ATP:sulfate adenylyltransferase Registry number: EC 2.7.7.4 (12 Dec 1998) |
| ATP synthase | <enzyme> An enzyme that catalyses the conversion of phosphate and ADP into ATP during oxidativephosphorylation in mitochondriaand bacteria or photophosphorylationin chloroplasts. (09 Oct 1997) |
