2. Describe the structure of hemoglobin using the words globin, heme, & oxygen.

Answers

Answer 1

Explanation:

Each hemoglobin molecule is made up of four heme groups surrounding a globin group, forming a tetrahedral structure. ... There are four iron atoms in each molecule of hemoglobin, which accordingly can bind four atoms of oxygen. Globin consists of two linked pairs of polypeptide chains.

Answer 2
Hemoglobin, also spelled haemoglobin, iron-containing protein in the blood of many animals—in the red blood cells (erythrocytes) of vertebrates—that transports oxygen to the tissues. Hemoglobin forms an unstable reversible bond with oxygen. In the oxygenated state, it is called oxyhemoglobin and is bright red; in the reduced state, it is purplish blue. Hemoglobin develops in cells in the bone marrow that become red blood cells. When red cells die, hemoglobin is broken up: iron is salvaged, transported to the bone marrow by proteins called transferrins, and used again in the production of new red blood cells; the remainder of the hemoglobin forms the basis of bilirubin, a chemical that is excreted into the bile and gives the feces their characteristic yellow-brown colour. Each hemoglobin molecule is made up of four heme groups surrounding a globin group, forming a tetrahedral structure. Heme, which accounts for only 4 percent of the weight of the molecule, is composed of a ringlike organic compound known as a porphyrin to which an iron atom is attached. It is the iron atom that binds oxygen as the blood travels between the lungs and the tissues. There are four iron atoms in each molecule of hemoglobin, which accordingly can bind four atoms of oxygen. Globin consists of two linked pairs of polypeptide chains. Hemoglobin S is a variant form of hemoglobin that is present in persons who have sickle cell anemia, a severe hereditary form of anemia in which the cells become crescent-shaped when oxygen is lacking. The abnormal sickle-shaped cells die prematurely and may become lodged in small blood vessels, potentially obstructing the microcirculation and leading to tissue damage. The sickling trait is found mainly in people of African descent, though the disease also occurs in persons of Middle Eastern, Mediterranean, or Indian descent.

Between 1991 and 2010, an average of 16 cases linked to tainted drinking water were reported annually by the CDC and Environmental Protection Agency (EPA).

In addition to microbiological infections, common drinking water contaminants include a wide range of substances that may not just be poisonous in drinking water but also have negative impacts on fish and animals. Many chemicals, such the copper in Minamata Bay and the PCBs in the Columbia River, have been dumped into rivers as industrial waste.

Why are plyometrics best performed on grass playing fields, basketball courts, or tartan tracks?

Answers

Plyometrics are best performed on grass playing fields, basketball courts, or tartan tracks due to their superior shock absorption, energy return, traction, joint protection, and performance-enhancing properties.

Plyometrics, also known as jump training, are best performed on grass playing fields, basketball courts, or tartan tracks for several reasons.


1. Shock absorption: Grass playing fields, basketball courts, and tartan tracks provide better shock absorption compared to harder surfaces like concrete or asphalt. This is crucial because plyometric exercises involve rapid and explosive movements that generate significant impact on the joints and muscles. The softer surfaces help to reduce the stress on the body, minimizing the risk of injuries.

2. Energy return: These surfaces have some degree of elasticity, which allows them to absorb and then release energy. When performing plyometric exercises, the body relies on the stored energy from the stretch-shortening cycle. The softer surfaces help maximize the energy return, allowing for more powerful jumps and movements.

3. Traction: Grass playing fields, basketball courts, and tartan tracks offer better traction compared to slippery surfaces. Traction is important for maintaining stability and preventing slips or falls during plyometric exercises, which involve quick changes in direction and intense bursts of power.

4. Joint protection: The combination of shock absorption and energy return provided by these surfaces helps to protect the joints. The impact forces generated during plyometrics can put stress on the knees, ankles, and hips. The softer surfaces help to cushion these joints, reducing the risk of overuse injuries and minimizing joint discomfort.

5. Performance enhancement: Performing plyometrics on these surfaces can lead to improved performance in sports that require explosive power, such as basketball, soccer, or track and field. The optimal shock absorption, energy return, and traction provided by grass playing fields, basketball courts, or tartan tracks allow athletes to train more effectively, enhancing their jumping ability, speed, and agility.

In conclusion, plyometrics are best performed on grass playing fields, basketball courts, or tartan tracks due to their superior shock absorption, energy return, traction, joint protection, and performance-enhancing properties. These surfaces provide a safer and more effective environment for athletes to train their explosive power and improve their overall athletic performance.

Under normal conditions in the absence of vp infection, what is the structure of the molecule that binds and activates rac?

Answers

Under normal conditions in the absence of VP infection, the molecule that binds and activates RAC is known as the guanine nucleotide exchange factor (GEF).

The GEF molecule binds to RAC and facilitates the exchange of GDP (guanosine diphosphate) for GTP (guanosine triphosphate), thereby activating RAC. This activation triggers various cellular processes, such as cytoskeletal rearrangements and cell migration.

Guanine nucleotide exchange factors (GEFs) are primarily responsible for linking cell-surface receptors to Ras protein activation.

They do this by catalyzing the dissociation of GDP from the inactive Ras proteins. GTP can then bind and induce a conformational change that permits interaction with downstream effectors.

in contrast to the biopsychosocial model, the biomedical model views health as:_____.

Answers

In contrast to the biopsychosocial model, the biomedical model views health as the absence of disease or physical abnormalities.

The biomedical model of health is a traditional approach that primarily emphasizes the biological aspects of health and disease. It views health as the absence of disease or physical abnormalities in the body. According to this model, good health is achieved when there are no measurable signs of illness or pathology.

In the biomedical model, the focus is primarily on the diagnosis, treatment, and management of diseases through medical interventions such as medications, surgeries, and other medical procedures. It tends to prioritize objective measurements, laboratory tests, and physical examinations to identify and address specific biological abnormalities or dysfunctions.

In contrast, the biopsychosocial model of health recognizes that health and well-being are influenced by a combination of biological, psychological, and social factors. It acknowledges the interconnectedness of these domains and emphasizes the importance of understanding the individual as a whole, rather than solely focusing on physical symptoms or diseases.

By considering the biopsychosocial model, healthcare providers can take a more holistic approach to patient care, recognizing the influence of psychological and social factors on health outcomes and tailoring interventions accordingly.
