Really? I thought troponin played a bigger role in that.

Totally agree, it's all about those myosin heads.

Wait, isn't it the sarcomere that has the cross-bridges?
JA

Nope, definitely myosin. Can't believe that's even a question!
DO

Myosin has the most cross-bridges!

I keep mixing up troponin and myosin. I know troponin regulates contraction, but does it have cross-bridges too?

I practiced a question like this before, and I think it was myosin that had the most cross-bridges. It makes sense with how muscle contraction works.
DE

I’m not entirely sure, but I remember something about sarcomeres being the functional units of muscle fibers. Could they be involved?
LA
Laurel

I think the answer might be myosin because it’s known for forming cross-bridges during muscle contraction, right?

The question is asking about the muscle protein with the cross-bridges, so I'm pretty confident the answer is D. Myosin.
FA
Fannie

Myosin is the muscle protein that has the cross-bridges, so I'm going to go with D.

Hmm, I'm not sure about this one. I'll have to think it through carefully before answering.
BE

I think the answer is B. Sarcomeres contain the cross-bridges that allow muscle contraction.
PA

Actually, the correct answer is D) Myosin because it forms the cross-bridges in muscle contraction.

Myosin, no doubt. It's like the muscle's secret weapon, with all those cross-bridges ready to go.
EV

Myosin is definitely the muscle protein with many cross-bridges.
CL

Myosin, of course! That's the thick filament that forms all those cross-bridges. Easy peasy.
AL
Alecia
