What are hormones and how do they work could growth be manipulated?
Hormones are chemical substances that act like messenger molecules in the body. After being made in one part of the body, they travel to other parts of the body where they help control how cells and organs do their work. For example, insulin is a hormone that's made by the beta cells in the pancreas. When it's released into the blood, insulin helps regulate how the cells of the body use glucose (a type of sugar) for energy.
Growth can be manipulated in a way that growth hormone implants are used for people with pituitary problems. Steroids are used to make muscles bigger.
What is the function of the 3N tissue of an angiosperm?
The 3N tissue in angiosperms, also known as endosperm, serves as a nutrient reserve to support the developing embryo. It provides essential nutrients such as starch, proteins, and lipids to the growing plant embryo as it germinates and starts to grow.
Is fasting anabolic or catabolic?
Fasting is generally considered catabolic, meaning it promotes the breakdown of molecules for energy. During fasting, the body uses stored energy reserves like glycogen and fat for fuel. However, intermittent fasting can also have some potential anabolic effects, such as increasing growth hormone levels and promoting cellular repair processes.
What effect does substrate and enzyme joining have on chemical bonding?
enzyme catalyze the biochemical reactions by lowering their activation energy. An enzyme which take part in such reaction wont be lost or gained any chemical structure and it would be the same after the reaction.
d. photosynthesis Photosynthesis is the process by which plants, algae, and some bacteria convert carbon dioxide into organic molecules using sunlight as an energy source. This is the primary way carbon enters the web of life.
Which Cellular events occur during interphase?
The cell grows and the nuclear DNA is replicated.
Growth occurs in early interphase (the G1 stage) and late interphase (the G2 stage). DNA replication takes place during mid-interphase (the S stage).
Growth involves, among other processes, transcription of activated genes and translation of messenger RNA, resulting in protein synthesis.
The Cell carries out metabolic processes primarily concerned with Growth, and DNA is replicated during S-Phase, which is found between the G1 and G2 Phases.
Interphase begins with and ends with a Nuclear Division. Nuclear Division will not occur during Interphase.
What elements are found in phospholipids?
Phospholipids are composed of a phosphate group, glycerol molecule, two fatty acid chains, and a polar head group. These components interact to form a lipid bilayer structure that is a key component of cell membranes.
Is there any spiritual significance to laminin?
Truthfully no. The most that one can gather from a laminin is the diagram shape is of a cross. I have heard a few sermons and talks of how the laminin is a sign of God or a metaphor for the way Christ holds together the church, the world, or etc. I simply ask that we, as Christians, please leave these instances as merely metaphors. Do not use these in any apologetic conversations as they have no debatable merit.
What is a side chain of an amino acid?
Side chain = r group
All aa have carboxyl and amine groups alond with a side chain. Side chains are unique, differentiating one amino acid from another. It determines the properties like shape, pH, composition, etc
How many chromosomes does a human somatic cell have?
46 chromosomes arranged into 23 pairs at replication.
Result of mixing both enzymes with there substrates in a single test tube?
Mixing both enzymes with their substrates in a single test tube could result in the enzymes catalyzing their respective reactions simultaneously. This may lead to the production of different products depending on the specificity of each enzyme for its substrate. However, it is important to consider factors such as pH, temperature, and compatibility of the enzymes to ensure proper activity and prevent any interference between the reactions.
Where can proteins be found in the body?
I don't think they are stored. Obviously they are used to make structures such as muscle. If there is a dietary shortage of protein muscle can be broken down to provide amino acids. I have been told that small amounts of muscle tissue may break down in the short period of overnight fasting, and that this has encouraged dieticians to stress the importance of breakfast. I cannot give references for this and frankly consider it should be treated with caution.
What chemical elements make up protein?
Proteins are made up of carbon, hydrogen, oxygen, nitrogen, and in some cases sulfur. These elements combine in various arrangements to form different amino acids, which are the building blocks of proteins.
How does meiosis differ from mitosis?
Mitosis makes new cells that are used during growth, development, repair, and asexual reproduction.
Meiosis makes cells that enable an organism to reproduce sexually and happens only in reproductive structures.
They both lead to cell division, rest is different. Meiosis leads to reductional division, taking place in sex cells only while Mitosis takes place in somatic (body) Cells. Meiosis produces 4 daughter Cells and mitosis produces 2.
Which macromolecule makes up an enzyme?
Actually, proteins themselves are macromolecules. They are made of multiple polypeptide chains linked together. Polypeptide chains are then the result of multiple amino acids linked by peptide bonds between the amino groups and acid groups.
The development stages of proteins are divided into four stages:
1) Primary - A simple polypeptide chain of amino acids
2) Secondary - Polypeptide chains folded as a result of hydrogen bond influence. Commonly seen as either alpha helices (like the double helix of a DNA, but singular) or beta sheets(picture rectangles linked together to form a zigzagged, shingle-like form)
3) Tertiary - A even more complex form of polypeptide chains with many/multiple folds. At this point the protein is gaining a real shape and its purpose more specified.
4) Quaternary - Several tertiary forms combine into one more complex structure. The specific shape determines the proteins final purpose and tasks.
Basically proteins are jumbles of polypeptide chains which are combinations of the 20 various amino acids which are made of an amino group, variable group, acid group, and a hydrogen. The elements used are always Carbon, Hydrogen, Oxygen, Nitrogen, and sometimes Sulfur.
Which bond that stabalizes a proteins tertiary structure is the strongest?
Disulfide bonds are the strongest covalent bonds that stabilize a protein's tertiary structure. They form between cysteine residues that have sulfhydryl groups, creating a covalent linkage that can withstand denaturation forces.
Why is DNA replication called semi conservative?
DNA replication of one helix of DNA results in two identical helices. If the original DNA helix is called
the "parental" DNA, the two resulting helices can be called "daughter" helices. Each of these two daughter helices is a nearly exact copy of the parental helix (it is not 100% the same due to mutations).
DNA creates "daughters" by using the parental strands of DNA as a template or guide. Each newly synthesized strand of DNA (daughter strand) is made by the addition of a nucleotide that is complementary to the parent strand of DNA. In this way, DNA replication is semi-conservative, meaning that one parent strand is always passed on to the daughter helix of DNA.
What happens to the boiling point of water at higher elevations where atmospheric pressure is less?
The boiling point of water decreases at higher elevations where atmospheric pressure is lower. This is because the lower pressure makes it easier for water molecules to escape into the air, requiring less energy to reach the boiling point.
What organelle lacks enzyme needed for lipid breakdown in tay Sahs Syndrome?
The lysosome is the organelle that lacks the enzyme needed for lipid breakdown in Tay-Sachs disease. This genetic disorder results in the accumulation of lipid molecules in the lysosomes, leading to cellular dysfunction and damage, particularly in nerve cells.
Ribo-nucleotides [that make up Ribo Nucleic Acid] comprise ribose sugars, phosphate groups for chain bonding, and nitrogenous bases for information content and exchange.
2' deoxy-ribose sugar moieties comprise Deoxy-ribose Nucleic Acid.
If a nucleoside is different from a nucleotide I haven't been able to find it.
Nucleic acids are made up of nucleotides. Each nucleotide is composed of a sugar + a phosphate + a nitrogen base. The nitrogenous bases are Adenine which pairs with Thymine and Cytosine which pairs with Guanine. Nucleotide polymers, (chains of nucleotides) are made up of nucleotides linked to the -OH group on the 3' carbon of one nucleotide and the phosphate on the 5' of the following nucleotide. The two chains in a double helix run antiparallel to one another.
What substance is necessary for the synthesis of most material in an organism?
Carbon is a necessary substance for the synthesis of most material in an organism. It forms the backbone of organic molecules like proteins, carbohydrates, and lipids, which are essential for the structure and function of living organisms.
What molecule do you remove from glucose and fructose to make sucrose?
To make sucrose, a molecule of water is removed from glucose and fructose. This dehydration reaction results in the formation of a glycosidic bond between the glucose and fructose molecules, creating sucrose.
Why is taking fresh fruit and vegetables from vitamin c better than taking tablets?
Well, it's better to eat fruit, and see if you get the decent amount of vitamin C that you want, instead of taking a risk of eating a tablet for it, and get sick or something. Hope this helps! : )
