Biochemistry

Biochemistry is the study of the structure, composition and chemical processes in all living organisms. It covers the structures and functions of various cellular components, including proteins, carbohydrates, nucleic acids, lipids, and other biomolecules.

8,065 Questions

Define and explain the concept of biochemistry?

Biochemistry is the branch of science that focuses on the chemical processes and substances that occur within living organisms. It explores how biological molecules like proteins, carbohydrates, lipids, and nucleic acids interact and function in various cellular processes, such as metabolism and gene expression. Biochemistry helps us understand the molecular basis of life and how living organisms maintain homeostasis.

Is Cellobiose is reducing or non reducing sugar?

Cellobiose is a reducing sugar because it has a reducing aldehyde group present in its chemical structure. This aldehyde group can undergo oxidation reactions, making cellobiose a reducing sugar.

Chloroplasts are to plants as what are to aerobic respiration?

Mitochondria are to aerobic respiration. Mitochondria are responsible for producing ATP through cellular respiration in eukaryotic cells, similar to how chloroplasts are responsible for photosynthesis in plant cells.

What happens if you have too much thiamine?

Some say that it will affect your health, and that you could get herpes from it. But scientists have discovered that with too much thiamine in your system you could put too much stress on your bodily fluids therefore, getting a disease known as _______ which I don't know. Though as you may know thiamine is just a nutrient which is found in many foods, but sometimes if you "overdose" it, it can be harmful to your body. There is some person I met they only live near me and they said because of having too much thiamine it has affected their bodily fluid AND given them herpes, which as you know isn't good at all... Thankyou for using I have all the answers to you solutions.

What does the hormone Atrial natriuretic peptide do?

It inhibits release of renin from the kidneys and of aldosterone from the adrenal cortex.

The result is increased excretion of sodium ions and water from the kidneys and lowered blood volume and blood pressure. Or what you might be looking for is all of the above. :)

What is the difference between a hemiacetal and a hemiketal?

The main difference between a hemiacetal and a hemiketal is the functional group involved. A hemiacetal forms when an alcohol group and an aldehyde group are involved, while a hemiketal forms when an alcohol group and a ketone group react. Additionally, in a hemiacetal, one oxygen atom is part of the alcohol group and one is part of the aldehyde group, whereas in a hemiketal, both oxygen atoms are part of the alcohol group.

What happens when you burn a monosaccharide?

When you burn a monosaccharide, such as glucose, it undergoes combustion and reacts with oxygen to produce carbon dioxide, water, and energy in the form of heat and light. This process releases stored energy from the bonds within the monosaccharide molecule.

Where is the nitrogen atom in a double helix?

Nitrogen atoms are present in the nucleotide bases that make up the rungs of the DNA double helix. Specifically, the nitrogen atoms are found within the purine (adenine, guanine) and pyrimidine (cytosine, thymine) bases that pair with each other to form the double helix structure.

What the equation for the reaction catalyzed by catalase?

This is the decomposition reaction of hydrogen peroxide:
2 H2O2 = 2 H2O + O2

Result of Nylander's test in glucose?

Nylander's test is used to detect reducing sugars like glucose in a given sample. A positive result in the Nylander's test indicates the presence of reducing sugars, including glucose, causing a color change to give a brown or red precipitate.

Why the pH of stacking gel and resolving gel are different?

Stacking gel has a different pH from resolving gel because stacking gel is made out of Tris?HCI buffer which has a pH of 6.8. This makes sure that it is about 2 units different from the pH of resolving gel.

What products of aerobic cellular respiration are used by plants?

Plants use the products of aerobic cellular respiration, including ATP (adenosine triphosphate) and carbon dioxide, as sources of energy for various physiological processes such as growth, metabolism, and reproduction. Additionally, the water produced during respiration is utilized by plants for processes like photosynthesis and transpiration.

What molecules contain the codons?

Codons are found in mRNA molecules, which are transcribed from DNA molecules during protein synthesis. Each codon corresponds to a specific amino acid or a signal for the start or end of protein synthesis.

What is the product of the dehydration synthesis of 2 amino acid molecules is a molecule that consists of two amino acids bonded together?

The product of the dehydration synthesis of 2 amino acids is a dipeptide. During dehydration synthesis, a water molecule is removed as the amino groups of two amino acids react, forming a peptide bond between them.

What is chemical formula of sulphuric acid?

H2SO4. In sulphuric acid, the S atom has a valence of 12 electrons. Two of the O atoms are attached to the S atom through double bonds. The other two O atoms are hydroxy ("-OH") oxygen atoms that are attached the S atom through a single bond.

Does mature mammalian RBC have RNA?

No. As part of the RBC maturation process in mammals, the red blood cells loses its nucleus and is no longer able to synthesize RNA.

Immature RBC's, called reticulocytes, do still have small amounts of RNA. However, it is atypical to see more then 1% in a healthy blood smear.

Vitamins can be either water-soluble or lipid-soluble?

Yes, some vitamins are water-soluble, such as vitamin C and the B vitamins, and are easily absorbed and excreted by the body. Lipid-soluble vitamins, like vitamins A, D, E, and K, are stored in fatty tissues and are better absorbed with dietary fats. Both types are important for overall health and must be obtained through diet or supplements.

Predict the color of amylopectin in iodine solution and explain why they give each complex?

Amylopectin will turn blue-black in iodine solution because it is a branched polysaccharide made of alpha-glucose units. The iodine molecules form a complex with the helical structures of the amylopectin molecule, leading to the blue-black coloration due to the presence of multiple branching points.

In which fat-soluble vitamin is toxicity most frequently observed?

Vitamin A is the fat-soluble vitamin in which toxicity is most frequently observed. Excessive intake of vitamin A from supplements or high-dose medications over a prolonged period can lead to symptoms such as headache, dizziness, nausea, and liver damage.

Is amylase performing a catabolic or anabolic reaction?

As a matter of fact, we can consider both reactions:


When amylases (alpha and beta) perform the breakdown of starch during digestion, is considered to be a catalytic reaction.


Otherwise, when amylase breaks the glycosidic bond of glycogen, in order to provide glucose molecules to the metabolism, can be considered that carries out an anabolic process.

What ATP bond is broken to release energy?

ATP stands for Adenosine Tri-Phosphate. This means there are three phosphate groups stuck together on the tail of the molecule. Packing that many negatively charged groups together takes energy which is stored in the structure. When the bond between the second and third phosphates is broken, energy is released and the molecule becomes ADP or Adenosine Di-Phosphate.

In which tissue will lipid soluble compounds most likely be stored?

Lipid soluble compounds are most likely to be stored in adipose tissue, also known as body fat. Adipose tissue serves as a major site for storing excess energy in the form of lipids, providing insulation and acting as a cushion for organs.
