What happens during rigor mortis in terms of ATP and muscle contraction? Describe the process of deglutition. What are the three phases? Describe two integumentary system mechanisms that help regulate body temperature. Describe the renin-angiotensin mecha...
including downregulation of gene sets involved in skeletal muscle contraction, increased endoplasmic reticulum stress, and reduced utilization of specific metabolic pathways. We also defined a muscle transcriptional
Regulation of vertebrate skeletal muscle contraction involves the troponin-tropomyosin complex within the actin-based thin filament. Tropomyosin sterically blocks actin's binding site for myosin in the relaxed state, and the binding of Ca2+ to troponin induces a movement by tropomyosin away from this ...
Mammalian embryos exhibit sophisticated cellular patterning that is intricately orchestrated at both molecular and cellular level. It has recently become apparent that cells within the animal body display significant heterogeneity, both in terms of their
when myosin stays attached to actin for extended periods with minimal ATP usage. This allows smooth muscle to maintain a sustained contraction or tension without consuming much energy Describe a pacemaker potential. a gradual, spontaneous depolarization in certain cells (like in the heart), leading ...
The generated mechani- cal force can be used either to carry cargos (e.g. vesicles, organelles, proteins, RNA, or chromosomes), or to shift cytoskeletal elements (e.g. during muscle contraction and in contractile stress fibers or microtubule sliding within the mitotic spindle). Three ...
Mutant Skeletal Muscle Protein Expression Introduction Actin filaments are major components of the cytoskeletons of all eukaryotic cells and play key roles in a variety of cellular functions, including cell migration, organelle transport, and muscle contraction. These diverse processes depend on the dynam...
The final gene matched an ATP synthase subunit suggestive of higher initial energetic needs of colony founders. The remaining genes analyzed showed biases primarily in the early larval stage library. Most of the genes that matched are involved with general energy production and muscle contraction [26...
(e.g. carbohydrates) and oxygen, mitochondria may become increasingly unable to supply sufficient ATP to power cardiac muscle contraction in spiny lobsters. Although not measured in this study, cardiac contraction strength declines along with stroke volume in heat stressed American lobster heart12, ...
