Samenvatting Biochemie blok 1.4
Leerdoelen
De student kan:
 Het proces van de glycolyse beschrijven.
Glycolyse is de eerste stap in de koolhydraat metabolisme.
Glucose (C6H12O6) wordt afgebroken en 2 pyruvaat wordt gevormd.

De glycolyse bestaat uit 10 stappen.
Er zijn 2 fases.
1. Zodra glucose de cel ingaat wordt het gekoppeld aan fosfaat om te voorkomen dat glucose
de cel uit gaat. Glucose wordt dan Glucose-6-fosfaat.
Fase 1 kost 2 ATP.
2. In fase 2 wordt uiteindelijk pyruvaat gevormd.
Fase 2 levert 4 ATP
De netto opbrengst van de glycolyse levert dus 2 ATP(adenosinetrifosfaat).
Tijdens de glycolyse wordt 1 glucose molecuul omgezet tot 2 moleculen
pyruvaat(pyrudruivenzuur).

De verbranding van glucose vindt plaats in het cytoplasma van de cel.

 Uitleggen welke delen van het proces aeroob/anaeroob zijn.
Alleen glycolyse is anaeroob (zonder zuurstof) en vindt plaats in het cytoplasma. De andere 3
processen zijn aeroob(met zuurstof) en vinden plaats in het mitochondrium.

Glycolyse Proces I Zet glucose om in 2 pyrodruivenzuur
Anaeroob Cytoplasma

Oxidatieve decarboxylering Proces II Zet pyrodruivenzuur om in Acetyl-CoA
Aeroob in het mitochondrium

Citroenzuurcyclus Proces III Zet AcetylCoA om in Oxaalazijnzuur*
Aeroob in het mitchondrium

Ademhalinsketen/oxidatieve fos. Proces IV Zet H+ ionen om in CO2, H2O en 36/38 ATP
Aeroob in het Mitochondrium


In de Oxidatieve decarboxylering vormen
Pyrodruivezuur, NAD+ en coenzym A (CoA)
samen acetyl-CoA, NADH en CO2.
