Why is the blood red in color?

Biology
1 answer:
nasty-shy [4]3 years ago
5 0

Answer:

human blood is red because of the protein hemoglobin, which contains a red-colored compound called heme that's crucial for carrying oxygen through your bloodstream. Heme contains an iron atom which binds to oxygen; it's this molecule that transports oxygen from your lungs to other parts of the body.

If an enzyme inhibitor binds at a site other than the active site of the enzyme, the nature of the inhibitor is described as
icang [17]

Answer:

B. non-competitive

Explanation:

As opposed as competitive inhibition, the non-competitive one does not bind with the active region of the enzyme. However, it does reduce the efficiency of the reaction because it changes the protein structure, making it unavailable for substrate.

Reversibility is related to the possibility of the reaction to be undone. If the bond is covalent, the enzyme will not return to its active state, so that would be a non-reversible bind.

What if a mutation occurred in the human insulin gene and the first codon was changed to CCG? Is
prohojiy [21]

Yes, this will be a silent mutation.

Explanation:

The mutation which occurred in the human insulin gene where the first codon was changed to CCG will be a silent codon because this will not change the sequence of the amino acid and the amino acids formed will remain the same.

A silent mutation occurs due to base substitutions resulting in a change in the nucleotide that does not impact the amino acid or protein formed once the mRNA is translated. The protein will retains its functional aspects.

With which part or parts of the heart do you think sympathetic and parasympathetic neurons form synapses? explain your reasoning
Softa [21]

The autonomic nervous system is the one that pertains to sympathetic vs parasympathetic. The autonomic nervous system has three divisions: the enteric nervous system, the sympathetic nervous system, and the parasympathetic nervous system.

Sympathetic is the nervous system responsible for your “fight or flight” responses in times of emergencies. It controls the body’s responses to stress, injuries, or perceived threats.

Parasympathetic is the nervous system responsible for your “rest and digest” responses in times of non-emergencies. It controls the body’s responses at rest and helps your body regulate its normal daily organ functions.

One way to remember how to distinguish between the two is to associate the beginning letters of the words with their corresponding attributes.

The sympathetic nervous system kicks in during times of stress, and the parasympathetic nervous system kicks in during times of peace.

Of course, there is much more to both nervous systems than that so let’s look a little bit closer at both.
