Myoglobin transfers oxygen obtained from hemoglobin to mitochondrial proteins involved in the catabolism of metabolic fuels to produce energy for the muscle cell. Using what you have learned in this chapter about myoglobin and hemoglobin, what can you conclude about the structures of these mitochondrial proteins

Answers

Answer:

Both are heteroproteins with a globular structure.

Explanation:

Both proteins are very similar, myoglobin is usually relatively small in size compared to hemoglobin.

Both proteins are considered heterogeneous because they are globular, because of their globular shape and the order of union between their amino acids.

The center of these proteins is iron, which is why they are capable of transporting gases such as oxygen, carbon dioxide (CO) and NO.

The structures that make them up are known as heme groups, these heme groups can also be found in meats of animal origin, it is as well as inside the erythrocyte, there is hemoglobin, which contains the heme group with a divalent iron capable of be oxidized to transport this oxygen in the form of oxide, towards the myoglobin that will receive it in the muscular tissue, and consequently oxygenate the muscular tissues as well as other tissues during locomotion or physical action.

what is the difference between Dopamine and Seratonin​

Both dopamine and serotonin are involved in your sleep-wake cycle. Dopamine can inhibit norepinephrine, causing you to feel more alert. Serotonin is involved in wakefulness, sleep onset, and preventing REM sleep. It's also required to produce melatonin.
dopamine brings feelings of pleasure and a happiness boost while serotonin is more of a stabilizer than a booster

dopamine primarily controls movement, and serotonin contributes to sleep and digestion

Answers

Answer:

She takes medication that increases the level of dopamine in the brain.

Hope it helps.

Sue has Parkinson's disease. She takes medication that increases the level of dopamine in her brain.

What is Parkinson's disease?

It is a neurodegenerative disorder characterized by a loss of dopamine-producing cells in the brain, particularly in an area called the substantia nigra.

Dopamine is a neurotransmitter that plays a crucial role in coordinating movement and regulating various brain functions.

In Parkinson's disease, dopamine deficiency leads to impaired communication between brain cells, resulting in the motor symptoms associated with the condition, such as tremors, stiffness, and difficulty with movement and coordination.

To address this dopamine deficiency, medications known as dopamine agonists or levodopa are commonly prescribed.

These medications work by increasing the levels of dopamine in the brain, compensating for the deficit caused by the disease.

Thus, Sue takes medications that increase the level of Dopamine.

which one of the following processes does not occur to excess neurotransmitters in the synapse

Answers

This question is incomplete because the options are not given; here is the complete question:

Which one of the following processes does not occur to excess neurotransmitters in the synapse?

A. Break down or digested into inactive fragments.

B. Collection by scavenger vesicles left over from the neurotransmitter release.

C. Drifting away from the synapse via diffusion.

D. Reuptake within the pre-synaptic neuron.

The answer to this question is B. Collection by scavenger vesicles left over from the neurotransmitter release.

Explanation:

The word synapse refers to the neurological structure that allows the transmission of signals or information between neurons. This process occurs through neurotransmitters, which are the molecules or substances with the messages.

Moreover, in this process, there can be in some cases excess. In this situation, the body reacts to this excess by degrading or breaking down the extra neurotransmitters, eliminating it through diffusion, or even reabsorbing it (reuptake). In this context, all are processes that occur due to excess neurotransmitters except collection by scavenger vesicles because in most cases neurotransmitters are simply absorbed or eliminated but there are not specialized scavenger vesicles that collect them.

c. Stay in circulation to speed up response to an antigen the next time
d. Stimulate Function of other T-cells and B-cells
e. Take in and process antigens binding them to MHC protein
f. Attack cells infected by viruses

Answers

Answer:

a. Make antibodies

Explanation:

B-cells is one of the two types of lymphocytes or white blood cells produced in the marrow of the bone (the other being T-cells). B-cells are a part of adaptive or acquired immunity in our body i.e. a learned defense after a pathogen might have penetrated.

B-cells help combat foreign Invaders that make way into the body by producing ANTIBODIES, which are specific to a particular pathogen. Note that, the B-cells learnt to combat based on a previous infection of such pathogen. In response to an antigen, the B-cells produce the plasma cells, which in turn produce the antibodies.
