Química IV Tarea: Introducción a BioquímicaNombre ____________________________________ Matrícula ________________
Contesta lo siguiente:
1. Menciona la diferencia entre anabolismo y catabolismo
2. Menciona tres diferencias entre los procesos metabólicos en organismos vivientes y las
reacciones tradicionales de la síntesis orgánica en el laboratorio.
3. Define reducción en términos de átomos de hidrógen y átomos de oxígeno ganados o perdidos
por el sustrato
4. En organismos vivientes, dos moléculas de acido 2-amino cisteína , HSC H 2 CH ( N H 2 ) COOH
, pueden combinarse para formar cistina, HOOCH(NH2)CH2S-SCH2CH(NH2)COOH. Menciona y
explica, en términos de perder o ganar átomos de hidrógeno, si la formación de cistina de la
cisteína es una reacción de oxidación o reducción.
5. Las siguientes reacciones redox representan la descomposición bacterial del desperdicio
orgánico bajo diferentes condiciones.
a. C6H12O6 + 6 O2 → 6CO2 + 6H2O
b. CH3COO⁻ + H20 → CH4 + HCO3 ⁻
Identifica el ambiente más probable (aeróbico o anaeróbico) para cada reacción
6. Explica la diferencia entre hidrólisis y reacciones de condensación
7. Completa y balancea la siguiente ecuación, e identifica su tipo de reacción (hidrólisis o
condensación)
