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.

Why do plants have different leaves and root systems?

This depends on the habitat in which they live if they live in an area with low rainfall then they would have tap root to penetrate deep down in the soil for water and in areas with high rainfall they would have fibrous roots.

How do you determine the chemical make up on the molecular level of a piece of corn?

The chemical makeup of a piece of corn can be determined by conducting chemical analysis techniques such as chromatography, mass spectrometry, and nuclear magnetic resonance (NMR) spectroscopy. These techniques help identify the specific molecules present in the corn, such as carbohydrates, proteins, lipids, vitamins, and minerals. Additionally, elemental analysis can provide information on the elemental composition of the corn.

Why enzymes are proteins?

Enzymes are proteins because they are made up of amino acids linked together in a specific sequence, forming a complex three-dimensional structure that allows them to catalyze chemical reactions. This structure is crucial for the enzyme's function and specificity in recognizing and binding to their substrate molecules. Enzymes can be denatured by changes in pH or temperature, highlighting their protein nature.

What organisms have a rough or smooth ER?

These two endoplasmic Reticulum functions are strictly internal to the Cell - all Organisms are comprised from Cells and the Cells composition is based upon the ongoing constructive activites of The Cellular Endoplasmin Reticulum - both Types.

Why can't animal Cells capture energy from sunlight and use it to make food?

Animal cells do get their energy from undertaking aerobic respiration. During this process, glucose is broken down in the presence of oxygen. The water and carbon dioxide released accompany energy.

What three elements are lipids made of?

The term "lipid" commonly refers to fats, which are known chemically as triglycerides. Triglycerides are organic molecules that contain three different types of elements: carbon, hydrogen, and oxygen.

But technically, lipids are a class of molecules that includes triglycerides, phospholipids, steroids, and waxes. So if you wanted to know what elements are found in lipids as a class, you'd have to allow for phosphorus as well, since phospholipids contain phosphorus in addition to carbon, hydrogen, and oxygen.

What happens if a cell goes through non-disjunction?

The failure of chromosomes to separate during mitosis results in one gamete that lacks a chromosome and another with 2 chromosomes. Gametes with improper number of chromosomes are called aneuploid gametes. Aneuploid gametes are the most common cause of spontaneous abortion and handfuls of other congenital disorders that varies depending on donors gamete content.

What are matching sets of chromosomes called?

Matching sets of chromosomes are called homologous chromosomes. These chromosomes have the same genes in the same locations but may have different versions of those genes. Homologous chromosomes are inherited from each parent.

What is the probablilty that a human sperm cell will carry an X chromosome?

The male gamete is comprised, on average, of 50% of the X chromosome and 50% of the Y chromosome.

Is lysine a lipid?

No, lysine is not a lipid. Lysine is an essential amino acid that is important for protein synthesis in the body, whereas lipids are a diverse group of molecules that include fats, oils, and waxes.

How does the electron transport chain during muscle exercises work?

when NADH and FADH is oxidized from the matrix of the mitochondria of the muscle cells h+ protons pass through proteins on the inner membrane of the mitochondria. the proton gradient made by this cause protons to come back down into the mitochondrial matrix by passing through a atpase that generates ATP(energy from adp) by using the work from the proton gradient. the ATP newly made by this atpase is the energy that the cells use for muscle activity.

Is mannose a disaccharides?

No, mannose is a monosaccharide, meaning it is a simple sugar consisting of a single sugar unit. It is not a disaccharide, which is a carbohydrate composed of two monosaccharide units.

What parts of the 2 amino acids are involved in dehydration synthesis?

The carboxyl (COOH) group of one amino acid and the amino (NH2) group of another amino acid are involved in dehydration synthesis to form a peptide bond. During this process, a water molecule is removed as the two amino acids join together.

Why is amber-colored glass commonly used as containers in pharmaceutical preparations?

Amber-colored glass is commonly used in pharmaceutical containers because it provides protection against light degradation, which can affect the stability and effectiveness of the medications stored inside. The amber color of the glass helps to filter out harmful UV rays that can cause degradation of light-sensitive medications. This makes it an ideal choice for preserving the quality and potency of pharmaceutical preparations.

Who pays a Toxicologist?

Toxicologists are typically paid by government agencies, academic institutions, research organizations, pharmaceutical companies, environmental consulting firms, and private industry clients who require toxicology expertise for risk assessment or product development.

Will an enzyme that breaks down starch work on an enzyme that breaks down protein?

Saliva contains amylase, which breaks down complex sugars such as starch. However starch can't ever be broken down into proteins. They are fundamentally different, starch is a polysaccharide while protein is a polypeptide.

What is domain enzyme?

There is no specific term like "domain enzyme." Enzymes are biological catalysts that speed up chemical reactions in living organisms. A domain in an enzyme refers to a specific region of the protein structure that has a particular function or substrate binding site.

Why do DNA strands have an asymmetrical structure?

DNA strands have an asymmetrical structure because of the specific pairing of nucleotide bases (A-T and G-C) in the double helix. This complementary base pairing results in two antiparallel strands that run in opposite directions, creating a helical structure with a major and minor groove. This asymmetry is essential for DNA replication and transcription processes.

What type of Cells undergo action potential?

Neurons are the main cells that undergo action potential. These specialized cells are responsible for transmitting electrical signals in the nervous system to communicate with other neurons, muscles, or glands.

Are catalyse Maltese and sucrose enzymes?

All enzymes end in -ase. Their substrate is the base for the enzyme. For example: the sugar maltose is acted on by the enzyme maltase. Sucrose, by sucrase.

What macromolecule family does the starch belong to?

Starch belongs to the carbohydrate macromolecule family. It is a polysaccharide composed of glucose units and serves as a storage form of energy in plants.

What is the type of endocytosis where an entire cell is engulfed?

Phagocytosis is the type of endocytosis where an entire cell is engulfed by another cell. This process is typically carried out by immune cells to ingest and eliminate pathogens or cellular debris.

What is the function of plasmids in DNA?

A plasmid is a small loop of DNA that contains genetic information to help bacteria perform functions such as making use of unusual food sources, resisting antibiotics meant to prohibit growth, or carrying the genes necessary to transfer DNA from one bacterium to another.
