🇲🇾 Malaysian Context🇲🇾 Konteks Malaysia

Yeast (fermentasi) is used in Malaysian food production — roti canai dough fermentation and tapai making use anaerobic respiration!Yis (fermentasi) digunakan dalam pengeluaran makanan Malaysia — doh roti canai dan pembuatan tapai menggunakan respirasi anaerobik!

Aerobic Respiration: Glucose to 38 ATP Glucose → Glycolysis Cytoplasm | 2 ATP → Krebs Cycle Matrix | 2 ATP → ETC Inner mem | 34 ATP Anaerobic: Yeast → Ethanol+CO2+2ATP | Muscle → Lactic acid+2ATP Aerobic=38ATP(with O2) | Anaerobic=2ATP(without O2) Oxygen debt = O2 to break down lactic acid | Fermentation in yeast

SPM 2022 Paper 2SPM 2022 Kertas 2

Explain why muscles ache after intense exercise. [4 marks]Terangkan mengapa otot sakit selepas senaman intensif. [4 markah]

📌 Exam Tip:📌 Tips Peperiksaan: Mention: oxygen deficit → anaerobic respiration → lactic acid accumulation → muscle fatigueNyatakan: defisit oksigen → respirasi anaerobik → pengumpulan asid laktik → keletihan otot
