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.

What two branches of science does biochemistry combine?

its a bit obvious Biology and chemistry (specifically organic chemistry)

Is a condensation reaction an anabolic reaction?

Yes, a condensation reaction is an anabolic reaction. It involves the formation of larger molecules from smaller ones by the removal of a water molecule. This process is common in the synthesis of complex molecules like proteins and carbohydrates.

What is a male gamete?

A male gamete is a specialized reproductive cell produced by males, such as sperm in humans. It contains half the genetic material necessary for reproduction and fuses with a female gamete (egg) during fertilization to form a new organism.

How many ATP molecules are formed for each glucose molecule metabolized aerobically?

Aerobic metabolism produces a net yield of around 30-32 ATP molecules per glucose molecule. This occurs through glycolysis, the citric acid cycle, and oxidative phosphorylation in the electron transport chain.

What events occurs during respiration?

During respiration, which includes both breathing and cellular respiration, the intake of oxygen and release of carbon dioxide take place. In breathing, air is inhaled through the nose and mouth, travels to the lungs where oxygen is taken up, and carbon dioxide is expelled. In cellular respiration, the oxygen taken up in the lungs is used by cells to produce energy, and carbon dioxide is produced as a byproduct.

Why are enzymes considered sufferior compared with other catalyzed?

Enzymes are not considered "sufferior." In fact, enzymes are highly efficient biological catalysts that facilitate chemical reactions in living organisms with great specificity and speed. They exhibit remarkable catalytic activity and can often perform their functions under mild conditions, making them ideal for many biological processes.

Does the nucleolus create ribosomes?

Yes, 'one step removed'.The Nucleolus is the site of intense synthesis of ribosomal Rna - this is Rna that exits the Nucleus and is assembled into Ribosomes within the Cytoplasm.

Ribosomes bind to smooth Endoplasmic Reticulum to make rough Endoplasmic Reticulum.

Nucleolus structure: Dense non-membranous mass composed of proteins, Dna, and newly synthesized rRna molecules.

Nucleolus function: Produces ribosomal RNA (rRNA) for ribosomes.
Yes they are made. Two parts are made seperate

In humans when a new cell is formed from a sperm cell an egg cell how many chromosomes does it have?

i think 26

i think 26

46 chromosomes. The sperm cell and egg cell each contain 23 chromosomes, totalling 46. The sperm cells and egg cells are known as haploid cells or sex cells (meaning having 1 set of chromosomes). Once the sperm cell and egg cell joins, a diploid cell is formed (meaning having 2 sets of chromosomes), and a zygote begins to form. The human body contains 2 sets of chromosomes, one maternal and one paternal.

Is hydroxyl hydrophobic or hydrophilic?

Hydroxyl -OH is Hydrophilic (attracts water). This is due to the electronegativity of the oxygen atom in -OH which makes the functional group polar. This polarity attracts the also polar H2O molecule creating a hydrophilic effect.

How does metal rust?

When water gets on metal an than dries quickly, some of the water turns into rust. Think of it this way if you leave the steam in the bathroom from the shower and it finally goes away...it turns into rust.

Is biotin a vitamin or a mineral?

Biotin is a vitamin, specifically Vitamin B7. It is an essential nutrient that plays a key role in metabolism, cell growth, and the production of fatty acids.

What are nucleotides made up of?

Nucleotides are made up of three components: a nitrogenous base, a five-carbon sugar (ribose or deoxyribose), and a phosphate group. The nitrogenous base can be adenine, thymine, cytosine, or guanine.

What are the optimum conditions for enzyme activity in the human body?

Enzyme activity in the human body is optimal at a specific temperature range around 37°C (98.6°F) and a pH range that varies depending on the enzyme but is typically around neutral (pH 7). Additionally, the presence of cofactors and coenzymes, as well as appropriate substrate concentrations, are crucial for optimal enzyme activity. These conditions ensure that enzymes can function efficiently and facilitate metabolic processes in the body.

How do crystals grow?

the first stage is when certain chemicals dissolve into water, then the water starts to evaporate and the crystals form columns that normally have either 4, 6 or 8 sides. sometimes little spikes of crystal grow out of the crystals even when there's no water there.

How are proteins stabilized in the folded structure?

Proteins are stabilized in their folded structure by various interactions such as hydrogen bonding, disulfide bridges, hydrophobic interactions, and electrostatic interactions between amino acid residues. These interactions help to maintain the unique three-dimensional shape of the protein, which is crucial for its function.

If a protein contains three polypeptide chains that are held together by bonding forces what kind of structure does the protein have?

The protein has a quaternary structure.

In addition, each polypeptide chain has a primary, secondary, and tertiary structure.

The primary structure is the sequence of amino acids in a chain.

The secondary structure is the next higher level of arrangement of a chain in space, for example coiling into a alpha-helix, shaping into a beta-pleated sheet, or forming into a turn or loop.

Tertiary structure is a yet higher-level folding of the chain into its final three-dimensional shape.

Some proteins have only one chain, but if there are two or more, the combination of these chains to form the functional protein is the quaternary structure.

What is the molecular weight of alpha amylase?

O peso molecular da α-amilase varia de 10 a 210 KDa, dependendo da sua

origem. As α-amilases microbianas apresentam peso molecular entre 50 e 60 KDa

(GUPTA et al, 2003), sendo que as α-amilases bacterianas apresentam variação de

28 a 78 KDa e as α-amilases fúngicas (41 a 69 KDa) de acordo com os resultados

de diferentes autores citados por PANDEY et al (2005).

What is the role of cAMP?

Cyclic adenosine monophosphate (cAMP) is a secondary messenger that plays a key role in intracellular signal transduction. It is involved in various cellular processes such as gene expression, metabolism, and cell growth. cAMP is synthesized by adenylyl cyclase in response to extracellular signals and activates protein kinase A to initiate downstream signaling pathways.

Human body cell?

(biology) the basic structural and functional unit of all organisms; they may exist as independent units of life (as in monads) or may form colonies or tissues as in higher plants and animals

device that delivers an electric current as the result of a chemical reaction

a small unit serving as part of or as the nucleus of a larger political movement

  • cellular telephone: a hand-held mobile radiotelephone for use in an area divided into small sections, each with its own short-range transmitter/receiver
  • small room in which a monk or nun lives
  • a room where a prisoner is kept

What are the components of lipids?

Lipids are mainly composed of fatty acids, glycerol, and various other molecules such as cholesterol, phospholipids, and triglycerides. They play a crucial role in storing energy, forming cell membranes, and acting as signaling molecules in the body.

What is the structure of an amino acid?

Amino acid is consist of an amino group, attached to a carbon with a hydrogen bonded to it.

The same alfa carbon is attached to a carboxylic acid and R(alkyl group)

The general formula is as follows

NH2-CHR-COO

How does photosynthesis work?

Plants take in water and carbon dioxide, and create oxygen.

Photosynthesis, is a process that converts carbon dioxide into organic compounds, especially sugars, using the energy from sunlight. Photosynthesis occurs in plants, algae, and many species of Bacteria, but not in Archaea.

What is meiosis?

Division of cells in which four "daughter" cells are produced from one "parent" cell, each with half the genes of the parent. Meiosis is a special kind of cell division that produces haploid (1n) cells. yah

What is proteins interaction?

Protein is a very important functional molecule of life. It is because it can interact with other protein(s), ions, and nucleic acids to carry out cellular processes. The chemical communication is usually accompanied by non covalent forces such as Hydrogen bonding, wander wall's interactions adn ionic binding.
