A 1-year-old baby has been hospitalised for body and limbs lesions. Examination revealed carnitine deficiency in the child’s muscles. A biochemical reason for this pathology is the disorder of:
- A. Utilization of lactic acid
- B. Oxidative phosphorylation
- C. Regulation of Ca2+ rate in mitochondria
- D. Transport of fatty acids to mitochondria
- E. Substrate-linked phosphorylation
Hint
Recall which kind of substrate carnitine shuttles across an intracellular membrane, and what muscle normally uses that substrate for.
