You are right, it is B because, endocrine glands, as part of the endocrine system, they regulate and maintain a constant equilibrium in our bodies, known as homeostasis.
I'd say that it is incorrect because each carbon atom should bond 4 times and all three carbon atoms in this structural formula only bond once. The reverse is true for hydrogen atoms. They only form one bond but in this structural formula two of them have four bonds. I don't know about nitrogen though.
Creatine, Caffeine, Branched-chain amino acids and Beetroot juice.
Creatine:
- Athletes frequently utilize creatine to enhance performance in weightlifting or sprinting. It might help with muscle healing and mass-building.
- Caffeine might increase mental clarity and lessen feelings of weariness.
- Leucine, isoleucine, and valine are branched-chain amino acids that may improve endurance performance by acting as a crucial energy source when carbohydrate levels are low.
- By increasing blood flow to working muscles, beetroot juice may improve athletic performance.
- By sustaining production in active muscles, creatine aids in ensuring a steady supply of energy to working muscles. Additionally, your heart, brain, and other tissues contain little amounts.
