16
Q

vacuola

A

presente solo en celula vegetal, recerva alimenticia

17
Q

sintesis de proteinas

A

el ARN mensajero copia informacion de una de las hebras del ADN dentro del núcleo, despues sale y le da la informacion a los ARN de transferencia y estos llevan aminoacidos a el ribosoma y ahi los ARN ribosomales crean tripletes de aminoacidos para despues dejarlas libres en el citoplasma

18
Q

de que carece la celula vegetal?

A

de centriolos

19
Q

que son los lípidos?

A

grasas, fosfolipidos, aceite, esteroides

20
Q

acidos nucleicos

A

ADN (2 hebras) acido desoxirribonucleico y ARN (1 hebra) acido ribunocleico

21
Q

bases nitrogenadas del ADN

A

guanina, adenina, CITOCINA, timina

22
Q

bases nitrogenadas del ARN

A

guanina, adenina, URACILO, timina

23
Q

que es una proteina?

A

molecula formada por cadenas de aminoacidos

24
Q

que es la glucolisis

A

ruptira de la molecula de glucosa en citoplasma
