Why does the cell need both mRNA and tRNA in order to synthesize a protein like hemoglobin?
DNA and RNA (m and t) are made of nucleotides. Proteins like hemoglobin are composed of amino acids.
The mRNA specifies the sequence information needed for making the hemoglobin protein. This information is a direct and temporary copy of information contained on a gene on DNA.
The tRNA is a separate molecule the carries an amino acid on it. It is like a mediator. It has sequence that matches to a small part of the sequence being specified by the mRNA. When the tRNA moves into the right position on the mRNA, the amino acid detaches from the tRNA and is added to the growing protein or polypeptide chain.

How are hemoglobin and hair are both proteins yet they have different structures?
Hemoglobin and hair are both proteins, but they differ in structure due to their distinct functions and the types of amino acid sequences they contain. Hemoglobin is a globular protein, composed of four subunits that enable it to transport oxygen in the blood. In contrast, hair is primarily made of keratin, a fibrous protein that forms long, stable chains, providing strength and structure. These variations in amino acid composition and arrangement lead to their unique three-dimensional shapes and properties.
The major function of ribosomes is to synthesize?
The major function of ribosomes is to synthesize proteins by translating messenger RNA (mRNA) into amino acids. Ribosomes can be found in both prokaryotic and eukaryotic cells, and they are composed of two subunits - the large and small subunits.
How animals and plants get protein?
Pretty much any living organism produces proteins since proteins are necessary for life. This includes everything from plants to fungi to microbes to cells. Viruses cannot produce proteins in and of themselves since they need their host's ribosomes to make their protein.
What are 2 important proteins in human body?
Hemoglobin is a protein that carries oxygen in red blood cells, while insulin is a protein that regulates blood sugar levels. Both proteins play crucial roles in maintaining proper body function.
Why are residues hydrophobic in myoglobin but hydrophobic in hemoglobin?
Myoglobin and hemoglobin both contain hydrophobic residues, but their distributions and roles differ due to their functions and structures. In myoglobin, hydrophobic residues are primarily located within the interior of the protein, stabilizing its compact structure and facilitating oxygen binding. In hemoglobin, hydrophobic residues also contribute to the stability of the protein, but they play a crucial role in the cooperative binding of oxygen through interactions between subunits. Thus, while both proteins have hydrophobic residues, their specific arrangements and functional implications vary according to their distinct roles in oxygen transport and storage.
Where do hemoglobin synthesize?
at the bone marrow and liver and it occurs in both the cell's mitochondria and cytosol
What complex protein can carry both carbon dioxide and oxygen in the circulatory system?
Hemoglobin
What are the differences between collagen and hemoglobin?
Collagen is a long fibrous structural protein. A molecule of collagen contains three of the helical subunits coiled around each other in what is known as a coiled-coil. Hemoglobin on the other hand is a globular protein that contains a heme group. Four globular subunits make up hemoglobin and each contain an iron in order to hold the oxygen for transport.
How many amino acids would you expect to find between the hemoglobin of a human and a wolf?
There are no differences in the amino acids in human hemoglobin and wolf hemoglobin.
What are the two food values needed for the formation of haemoglobin?
Hemoglobin is a protein and it has an iron ion that can attract an oxygen molecule to it. Both proteins and iron can be found in food.
Do both plants and animal cells have ribosomes?
Yes they both do.
What change occurs in hemoglobin upon respiration?
The iron molecule (that's the hemo- in hemoglobin) gains and/or loses an oxygen molecule. The protein part (that's the globin) changes shape a bit. Both changes are very reversible and requires little energy.
What a hemoglobin AIC lab test tells the health care provider?
A hemoglobin A1C test tell your health care provider the percentage of your blood protein that is covered in sugar. It is used to diagnose both Type 1 and Type 2 Diabetes.

Which of the following is a characteristic of both hemoglobin and hemocyanin?
The two molecules transport oxygen in cells, hemoglobin being the iron-based protein found in the blood of mammals, while hemocyanin is a copper-based compound found in some invertebrates, including mollusks and some crustaceans.
Is human hemoglobin different from a mouse hemoglobin?
practically no difference. In both the hemoglobin has the same job, bonding with oxygen.
What is hemogiobin?
Hemoglobin is a protein carried by red blood cells to pick up oxygen in the lungs and deliver it to the peripheral tissues and maintain the viability of cells. it is made from two similar proteins that "stick together". these proteins must both be present for the hemoglobin to pick up and release oxygen. One of the proteins is called alpha, the other beta. Before birth, the beta protein is not expressed. A hemoglobin protein found only during fetal development, called gamma, substitutes up until birth. HemogLobin is the part of red blood cells that picks up oxygen in the lungs and releases it in your muscles, or wherever else it is needed.
