Question
Strike out the wrong options (Le. blood is red/blue) and Fill in the Blanks! (9 points) A sufficiently high intracellular Ca^2+ / Na^+ concentration is required to permit a muscle to contract. Ca^2+ has to bind to TROPONIN / TROPOMYOSIN / TROPOACTININ in order to induce a _________________________________________________ change in the complex formed by this molecule forms and TROPONIN / TROPOMYOSIN I TROPOACTININ. This change in the complex conformation is required to open the binding sites for myosin HEADS / TAILS / NECKS on the _______________________________________ Upon binding potential energy stored in MYOSIN HEADS / ATP / PROTON GRADIENT is used to pull the two filament types along each other and the muscle shortens.Explanation / Answer
I'll write the correct answers ok.
Ca2+
Troponin is calcium ion binding protein
inducing conformational changes
tropomyosin-troponin complex
myosin heads
on the thin actin filaments
stored in ATP
