What lipids is used for energy storage-glycolipids glycerophospholipids csphingolipids triacylglycerols spingophospholipids?

Triacylglycerols (TGs) are the primary lipids used for energy storage in the body. They consist of a glycerol molecule attached to three fatty acid chains and are stored in adipose tissue until they are broken down for energy production.

What is the main starting material for the glycolysis pathway?

The main starting material for the glycolysis pathway is glucose, a simple sugar that can be broken down to produce energy in the form of ATP. Glycolysis is the first step in cellular respiration and takes place in the cytoplasm of cells.

What is a proper serving size of protein?

A proper serving size of protein is typically around 3-4 ounces for most people. This is roughly the size of a deck of cards or the palm of your hand. It's important to consider your individual needs and dietary goals when determining the appropriate amount of protein to include in your diet.

What is the name of the waxy lipid covering plants?

The cuticle. This layer is composed of cutin, and is chemically a hydroxy fatty acid. The cuticle helps the plant retain water and can have a bluish cast, depending on the species of plant.

What is a product if cellular respiration and not fermentation?

The end products of cellular respiration are carbon dioxide, water, and ATP (adenosine triphosphate). These products are generated through the breakdown of glucose and other organic molecules in the presence of oxygen in the mitochondria of the cell. Fermentation, on the other hand, produces end products such as alcohol or lactic acid in the absence of oxygen.

What hormone that helps speed up your heart and breathing to help you when you sense danger?

Hormones come from organs and glands, they get controlled by the brain, the brain is monitored by your mind, and the boss of your mind is you, a spiritual being. Body, mind, spirit gets well explained in the book Fundamentals of Thought, you ought to test it out.

What would happen at molecular level if DNA polymerase and RNA polymerase enzymes collided?

If DNA polymerase and RNA polymerase enzymes were to collide, it could disrupt the replication/transcription processes. The collision may lead to stalling of the enzymes, potentially causing errors in copying genetic information and impairing the cell's ability to produce functional proteins. This could have detrimental effects on cell function and viability.

What is the advantage of restriction enzyme sites being palindromic?

Palindromic restriction enzyme sites are advantageous because they read the same on both strands of DNA, making them easier to identify and use for cutting DNA at specific sequences. This symmetrical nature ensures that the enzyme can cleave at a particular site regardless of the orientation of the DNA fragment.

What is the major drawback for a single cell?

The major drawback of a single cell is that it may be limited in size and complexity compared to multicellular organisms, as it must perform all necessary functions within a single cell. This can restrict the ability to specialize and perform more complex tasks efficiently.

How does one refer to the organ or structure toward which the effects of a hormone are directed?

Target organ can be defined as the organ or structure toward which the effects of a hormone are primarily directed. The target organ's activity levels demonstrate change in the course of biofeedback.

What is cause of faster protein migration in electrophoresis?

The main factors that can cause faster protein migration in electrophoresis are higher voltage, smaller pore size of the gel matrix, and lower molecular weight of the protein. These factors can increase the speed at which proteins move through the gel during electrophoresis.

What major role does glucose play in you body?

Glucose serves as the primary source of energy for the body's cells, providing fuel for metabolic processes and organ functions. It is particularly important for the brain, which relies almost exclusively on glucose for energy. Additionally, excess glucose can be converted into glycogen for storage in the liver and muscles to be used when needed.

Why is insulin called a hormone of abundance?

bcoz without insulin secreation glucose concentration in the blood is high, and no energy can be store in body, bcoz glucose is our ultimate energy,

also without insulin , heart attacks occur and BP high.

and beta cell secrete insulin.

What is the sight for protein synthesis?

Protein synthesis occurs at ribosomes, which are located in the cytoplasm of the cell. In eukaryotic cells, protein synthesis can also take place in the rough endoplasmic reticulum. The process involves translating the genetic information stored in mRNA into a specific sequence of amino acids to build a protein.

What is involved in the inter-chain linkage between complementary strands of DNA?

Inter-chain linkage in DNA involves hydrogen bonding between complementary nitrogenous bases (A-T and C-G) on opposite strands. This forms a stable double helix structure. The sugar-phosphate backbones of the two strands run antiparallel to each other, creating a strong and stable connection between the two DNA strands.

What might be different about getting DNA from bacteria or animals than getting it from plants?

The main difference is the cell wall composition. Bacteria and animals don't have cell walls, making it easier to extract DNA. In plants, the cell wall must be broken down first before DNA extraction can occur. Additionally, different methods and reagents may be required for extracting DNA from bacteria, animals, and plants.

What is the hormone that prefers us to fight or flee?

The hormone that prompts the fight-or-flight response is adrenaline, also known as epinephrine. It is released by the adrenal glands in response to stress or perceived danger, and it prepares the body for a quick physical response to a threat.

What type of chemical reaction is used to put DNA nucleotides together to make DNA?

The backbone of the DNA strand (referred to as phosphate-deoxyribose backbone) is made of alternating phosphate and sugar residues (2'-deoxyribose). The sugars are joined together by phosphate groups via phosphodiester bonds between adjacent sugar rings. The double helix is stabilized by hydrogen bonds between the bases attached to the two strands. A base attached to a sugar residue, which in turn attached to a phosphate group is referred to as a nucleotide.

What is a sugar group of RNA?

A sugar group in RNA refers to the ribose sugar molecule that forms the backbone of the RNA molecule. It is a crucial component that helps make up the structure of RNA, along with the phosphate group and nitrogenous bases. The ribose sugar in RNA differs from the deoxyribose sugar in DNA by having an extra hydroxyl (-OH) group.

How is identity obtained from Dna?

Identity can be obtained from DNA through DNA fingerprinting, which analyzes specific regions of an individual's DNA to create a unique genetic profile. This profile can then be compared to other samples to determine relatedness or identity. DNA is inherited from our parents and is unique to each individual, making it a powerful tool for identification purposes.

How many chromosomes does a somatic -diploid- corn Cell have?

Short Answer is: twice the number of Chromosomes as found in the gametic [Haploid] Cells.

What are the Elements and the essential elements of amino acids?

Two Part Question: Regarding Elements: Take Carbohydrates [C and H and O] and add Nitrogen and we get amino acids which are the constituent building blocks of Proteins.

The essential elements of amino-acids that comprise Proteins are i) the unique -C-C-N-C-C-N-C-C-N- [poly] - Peptide Bonds, and ii) the side chain [also called the -R group] that is attached to the free [outward pointing] Nitrogen bond.

What relationship exists between the cytoplasm of a cell and gylcolysis?

Glycolysis occurs in the cytoplasm of a cell. It is the first step in cellular respiration where glucose is broken down to produce energy in the form of ATP. The enzymes required for glycolysis are present in the cytoplasm of the cell.

How do cellulose and enzymes tie together?

Enzymes are needed to break down cellulose, which is a complex carbohydrate found in plants. Cellulase enzymes specifically target the beta-glycosidic bonds in cellulose molecules and break them down into simpler sugars like glucose. This process allows organisms to extract energy from cellulose through digestion or fermentation.

Which is a type of protein?

Protein is a class of organic compound that considered to be the building block of life. All living organisms have proteins, which are long chains of amino acids. The other types of organic compounds essential for life are carbohydrates and fats. When you eat food to sustain your life, you consume all three of these very important types of food.

Protein is found in large quantities in such things as: meat, dairy, eggs, fish, legumes, and soy products.

It is generally recommended that at each meal, there should be at least a small quantity of protein, since proteins are an essential ingredient in a healthy body.

Protein isn't exactly a type of anything. There are ,however, different types of protein such as, enzymes and structural protein (e.g. actin for the cytoskeleton)

Proteins are built up of long polypeptide chains of amino acids joined together by ester bonds. The type of protein produced is dependant on the kinds of amino acids it contains.
