<span>The man has been contracted with pseudo membranous colitis which is the result of taking broad-spectrum antibiotics for an infection caused by a gunshot wound to the abdomen; this is because normal micro biota is wiped by the antibiotics resulting the overgrowth of Clostridium difficile in colon.</span>

The major components of tendons, ligaments, and muscles are? a. proteins b. carbohydrates c. fats d. fiber

Hunter-Best [27]

The major components of tendons, ligaments, and muscles are proteins.

Hence, option A is correct answer.

<h3>What is Pyruvate Dehydrogenase? </h3>

The reaction between pyruvate and a lipoamide, which results in acetylated dihydrolipoamide and carbon dioxide, is catalysed by the enzyme pyruvate dehydrogenase. Thiamine pyrophosphate is a coenzyme needed for the conversion.

The pyruvate dehydrogenase complex changes the chemical pyruvate, which is created when carbohydrates are broken down, into the molecule acetyl-CoA. The chain of chemical events that provide energy for cells must start with this conversion.

<h3>What is glycolysis? </h3>

The metabolic process that changes glucose into pyruvate is known as glycolysis. The high energy molecules adenosine triphosphate and reduced nicotinamide adenine dinucleotide are created using the free energy released during this process. A series of ten enzyme-catalyzed processes make up glycolysis.

Not producing adenosine 5′-triphosphate is not the primary goal of glycolysis; rather, it is to produce pyruvate for the trichloroacetic acid (TCA) cycle.

By raising the proportion of NADH, a reduced form of NAD+ (nicotinamide adenine dinucleotide), to NAD+, the glycolytic synthesis of pyruvate lowers the cytosol.

What affect does binding a gas to a hemoglobin have on homeostasis

frutty [35]

Explanation:

Haemoglobin acts as a protein buffer.

Haemoglobin- oxygen binding in the blood is part of acid-base homeostasis. The cells within the brain or CNS ensure that more oxygen is taken into the lungs at a faster rate while carbon dioxide is removed; this aids in gaseous exchange and maintaining the pH of the blood- oxygen concentrations are kept high within the blood stream as blood circulates through the body.

Blood pH levels are typically within 7.35 --7.45. it is regulated by coordinated activity controlled by the brain, and carried out by the kidneys and lungs; along with red blood cells. When the body needs more oxygen, CO2 (as waste from cellular respiration), in the blood is converted to biarbonate increasing acidity; at the same time, H released in the reaction, and buffered by haemoglobin.

-The haemoglobin undergoes reduction by oxygen, and the pH level is maintained.

Further Explanation:

A typical oxygen disassociation curve shows haemoglobin’s percentage saturation at different oxygen concentrations (partial pressures). This shows the equilibrium between oxyhaemoglobin (haemoglobin in its oxygen bound state and haemoglobin (free of oxygen molecules). The saturation generally increases with increased partial pressures of oxygen.

Haemoglobin is an oxygen binding protein comprising four iron-based peptide subunits: two α subunits and two β subunits. Each molecule of haemoglobin has the ability to bind up to four oxygen molecules at a time; this occurs via cooperative binding- meaning that with increased haemoglobin- oxygen binding at the protein haemoglobin’s subunits,(where oxygen is a ligand) there is an increase in its affinity for oxygen.

This is because there is a conformational change in the hemoglobin molecule due to the altered orientation of the protein’s secondary structures, making it easier for a second molecule of oxygen to successively followed by more O2-Haem binding until the molecule is saturated- at this point the curve plateaus- it reached its carrying limit.

Hormones bind to chemical receptors in order to cause specific changes in target cells, these lead to changes in the body's internal environment called homeostasis. It includes the thyroid, parathyroid, pituitary, pineal and adrenal glands along with other regions.
