The upper motor neurons are axons that carry action potentials from the upper brain (cerebrum) to the brainstem or spinal cord A reflex is an automatic response to a stimulus produced by a reflex arc The lower motor neurons have cell bodies in the anterior horns of the spinal cord and in the brainstem These are all properties of reflexes except __________. A) reflex responses are very predictable. B) reflexes are responses to sensory inputs. C) reflexes are quick responses of the nervous...

Tropomyosin is long enough to cover the active sites on G-actin molecules. 7 Troponin complexes contain three globular polypeptides (TnI, TnT, TnC) that each have distinct functions. TnI __________________. binds to actin Troponin complexes contain three globular polypeptides (TnI, TnT, TnC) that each have distinct functions. TnT _________________. binds to tropomyosin and helps position it on the Factin strands The triad consists of __________________. T tubule and two parallel terminal ci...

Glycolysis Carbohydrates broken down to glucose. Series of chemical reactions in the cytosol that results in the breakdown of glucose into 2 pyruvic acid molecules. First Step of Glycolysis ATP loses a phosphate and is added to glucose making Glucose-6 phosphate. 6 carbons and 1 phosphate. Second Step of Glycolysis Another ATP loses a phosphate and is added to Glucose-6 phosphate making fructose 1, 6 Bisphosphate. 6 carbons and 2 phosphates. Third Step of Glycolysis Fructose 1, 6 Bispho...
