sans influx nerveux.","option_a":"Vrai","option_b":"Faux","option_c":"","option_d":"","option_e":"","option_f":"","bonne_reponse":"b","explication":"La contraction musculaire est déclenchée par un influx nerveux provenant des motoneurones.","points":1,"type":"qcm","actif":1,"section_id":null,"ordre":0,"_debug_answer_data_type":"string","_debug_answer_data_preview":"{\"correct\": \"b\",

liant à l'ATP ?","option_a":"L'actine","option_b":"La myosine","option_c":"La troponine","option_d":"La tropomyosine","option_e":"","option_f":"","bonne_reponse":"b","explication":"La myosine est une protéine motrice qui utilise l'ATP pour générer le mouvement des filaments d'actine.","points":1,"type":"qcm","actif":1,"section_id":null,"ordre":0,"_debug_answer_data_type":"string","_debug_answer_data_preview":"{\"correct\": \"b\", \"options\": {\"a\": \"L'actine\", \"b\":

(Na+)","option_b":"Potassium (K+)","option_c":"Calcium (Ca2+)","option_d":"Magnésium (Mg2+)","option_e":"","option_f":"","bonne_reponse":"c","explication":"Le calcium se fixe sur la troponine, ce qui permet aux sites de liaison de l'actine d'être exposés à la myosine, déclenchant la contraction.","points":1,"type":"qcm","actif":1,"section_id":null,"ordre":0,"_debug_answer_data_type":"string","_debug_answer_data_preview":"{\"correct\": \"c\", \"options\": {\"a\": \"Sodium (Na+)\",

musculaires lentes","option_b":"Les fibres musculaires rapides","option_c":"Les deux types de fibres","option_d":"Aucune des réponses","option_e":"","option_f":"","bonne_reponse":"b","explication":"Les fibres musculaires rapides (type II) sont recrutées pour les efforts intenses et brefs, comme lors d'un sprint.","points":1,"type":"qcm","actif":1,"section_id":null,"ordre":0,"_debug_answer_data_type":"string","_debug_answer_data_preview":"{\"correct\": \"b\", \"options\": {\"a\": \"Les fibres

:","option_a":"Vrai","option_b":"Faux","option_c":"","option_d":"","option_e":"","option_f":"","bonne_reponse":"a","explication":"La fatigue musculaire résulte d'une accumulation d'acide lactique, d'une déplétion en ATP et d'une baisse du pH dans le muscle.","points":1,"type":"qcm","actif":1,"section_id":null,"ordre":0,"_debug_answer_data_type":"string","_debug_answer_data_preview":"{\"correct\": \"a\", \"options\": {\"a\": \"Vrai\", \"b\":
