Lub acrosome yog ib qho tshwj xeeb membranous organelle nyob dhau ntawm qhov anterior ntawm cov phev nucleusuas tau txais txiaj ntsig zoo thoob plaws hauv evolution. Qhov no acidic vacuole muaj ib tug xov tooj ntawm hydrolytic enzymes uas, thaum secreted, pab cov phev nkag mus rau lub qe lub tsho tiv no.

Acrosome yog dab tsi thiab nws txoj haujlwm?

Nyob rau hauv tib neeg txiv neej phev, lub acrosome yog ib tug vesicle nyob rau ntawm nws lub ntsis. Nws muaj cov enzymes soluble proteolytic. Thaum cov phev los nyob rau hauv kev sib cuag nrog lub zes qe menyuam muaj acrosome cov tshuaj tiv thaiv. Cov tshuaj tiv thaiv no ua kom cov phev tawg los ntawm lub tsho tiv thaiv ntawm lub qe uas yog zona pellucida.

Acrosome nyob rau hauv phev nyob qhov twg?

Lub acrosome yog ib qho organelle uas tsim dhau ntawm ib nrab ntawm lub taub hau hauvcov spermatozoa (sperm cells) ntawm ntau cov tsiaj suav nrog tib neeg. Nws yog lub hau zoo li tus qauv muab los ntawm Golgi apparatus.

Acrosome nyob rau hauv cov phev cell yog dab tsi?

Lub acrosome yog ib yam tshwj xeeb ntawm organelle nrog lub hau zoo li tus qauv uas npog qhov anterior ntawm lub taub hau ntawm cov spermatozoon. Lub acrosome yog muab los ntawm Golgi apparatus thiab muaj cov enzymes digestive.

Lub luag haujlwm tseem ceeb hauv acrosome yog dab tsi?

Cov tshuaj tiv thaiv acrosome yog ib kauj ruam tseem ceeb hauv kev sib cuam tshuam gamete hauv txhua hom, suav nrog txiv neej. Nws tso cai rau spermatozoa nkag mus rau zona pellucida thiab fuse nrog oocyte membrane.
