A protein that holds a reserve supply of oxygen in muscle cells?

Troponin or the troponin complex is a complex of three regulatory proteins (troponin C troponin I and troponin T) that are integral to muscle contraction in skeletal muscle and cardiac muscle but not smooth muscle .Measurements of cardiac-specific troponins I and T are extensively used as diagnostic and prognostic indicators in the management of myocardial infarction and acute …

The reaction it catalyzes is: pyruvate + HCO − 3 + ATP → oxaloacetate + ADP + P. It is an important anaplerotic reaction that creates oxaloacetate from pyruvate. The enzyme is a mitochondrial protein containing a biotin prosthetic group requiring magnesium or manganese and acetyl CoA.. Pyruvate carboxylase was first discovered in 1959 at Case Western Reserve …

The mitochondrion (/ ˌ m aɪ t ə ˈ k ɒ n d r ɪ ə n / plural mitochondria) is a double membrane-bound organelle found in most eukaryotic organisms. Some cells in some multicellular organisms lack mitochondria (for example mature mammalian red blood cells ).A number of unicellular organisms such as microsporidia parabasalids and diplomonads have reduced or …

The mammalian hemoglobin molecule can bind (carry) up to four oxygen molecules. Hemoglobin is involved in the transport of other gases: It carries some of the body’s respiratory carbon dioxide (about…
