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 accomplishes the transmission of the nerve signal across the synapse?

The release of 'neurotransmitter substances' from an axon's perifery which traverse the synaptic cleft - the space between axon and adjoining dendrite - to both affect and effect the adjoining dendritic "perifery" which then re-initiates signal propagation to the next bunch of exonic nerve "endings".

What are marker enzymes of mitochondriya and chloroplast?

Some enzymes are present in certain organelles only; such specific enzymes are called as marker enzymes. After centrifugation, the separated organelles are identified by detection of marker enzymes in the sample.

Mitochondria=> Inner membrane: ATP Synthase.

Lysosome=> Cathepsin.

Golgi complex=> Galactosyl transferase.

Microsomes=> Glucose-6-phosphate.

Cytoplasm=> Lactate dehydrogenase.

The effects of hyposecretion and hypersecretion of adrenal cortex hormones result in what?

Hyposecretion of adrenal cortex hormones causes Addison's disease, that is weakness, fatigue and weight loss. Hypersecretion of adrenal cortex hormones causes increased blood glucose or Cushing's syndrome.

What is the compound formed when magnesium react with phosphorus?

The compound formed when magnesium reacts with phosphorus is magnesium phosphide (Mg3P2).

What process is used when combining aluminum with chlorine?

When combining aluminum with chlorine, the process of ionic bonding occurs. Aluminum loses electrons to become a positively charged ion (Al3+), while chlorine gains electrons to become a negatively charged ion (Cl-), resulting in the formation of aluminum chloride (AlCl3) through the attraction of opposite charges.

Where does the intermediate step of cellular respiration take place in a cell?

The intermediate step of cellular respiration, also known as the citric acid cycle or Krebs cycle, takes place in the mitochondrial matrix of the cell. This is where acetyl-CoA is further broken down to produce ATP, CO2, and high-energy electrons for the electron transport chain.

Why can differences in mitochondrial DNA be used as derived characters?

Derived characters are used to produce Information. Sperm Cells are too small to contain mitochondria so that the {in a fascinating way} the Dna that is only found in Mitochondria {in the Ovum} is not passed along to the male offspring. That's Why Sprite.

So that was the Intro.

If you can believe it the mitochondrial analysis shows that Humanity at one point {in Time} was at about one thousand Peoples.

Do bacteria have enzymes for performing metabolic activities?

Yes, bacteria have enzymes that help them perform various metabolic activities such as breaking down nutrients, synthesizing molecules, and releasing energy. Enzymes are essential for the functioning and survival of bacteria.

What is the dispersed phase in milk?

The dispersed phase in milk refers to the tiny droplets of fat suspended in the water-based liquid portion of milk. These fat droplets give milk its white color and contribute to its texture and flavor.

What causes Sanfilippo syndrome Type A?

caused by a deficiency of the enzyme heparan sulfate sulfamidase, due to mutations in the SGSH gene on chromosome 17. Type IIIA is felt to be the most severe of the four types, in which symptoms appear and death occurs at an earlier age

Does pH effect enzyme activity?

Yes it can.

Since enzymes are proteins, changes such as pH level, salinity, and even temperature can denature the proteins rendering them incapable of performing it's function because the shape has been altered.

What happens if you add too much proteinase k to a lysis buffer when performing DNA extraction?

Adding too much proteinase K can lead to excessive digestion of proteins in the sample, potentially reducing the effectiveness of subsequent DNA extraction steps. It can also result in degradation of the DNA itself, as proteinase K is an enzyme that can also digest DNA in high concentrations. It is important to carefully optimize the amount of proteinase K to prevent over-digestion of proteins and DNA.

What two kinds of plants do wheat rusts need to complete their life cycle?

Wheat rusts need two kinds of plants to complete their life cycle: wheat plants, which they infect and reproduce on, and barberry plants, which act as an alternative host where the rust can overwinter and produce spores that then infect wheat plants in the spring.

Where in the gel electrophoresis do you find larger fragments?

The larger the fragments the slower it migrates through the gel. Because it is bigger it takes longer to squeeze through the pores of the gel matrix. So the largest gel fragments will be at the top, closest to where the sample started.

What determines how many amino acids is in a polypeptide?

When a gene is transcribed there is a sequence of RNA bases that was copied from the DNA sequence. The RNA sequence can be exactly the same as the DNA or can be modified more in higher organisms by removing the introns if any. Three RNA bases is a codon. Each codon signifies an amino acid. There is an initiation codon and a terminal codon. So the amino acid sequence is determined by the sequence (multiple of 3 RNA bases) of codons between the initiation codon and termination codon.

What substances are directly involved in photosyntehsis?

The main substances directly involved in photosynthesis are carbon dioxide (CO2), water (H2O), and sunlight. These substances are utilized by plants to produce glucose and oxygen through the process of photosynthesis.

What is the food that contains high amount of vitamin zinc?

Zinc is found in oysters, and to a far lesser degree in most animal proteins, beans, nuts, almonds, whole grains, pumpkin seeds and sunflower seeds.

Other food that contain zinc:

  • Beef shanks
  • Crab, Alaska king
  • Pork shoulder
  • Breakfast cereal fortified,
  • Chicken leg, roasted
  • Pork tenderloin, cooked
  • Lobster, cooked
  • Baked beans
  • Cashews, dry roasted
  • Yogurt, fruit, low fat
  • Raisin bran
  • Chickpeas
  • Cheese, Swiss
  • Almonds, dry roasted
  • Milk
  • Chicken breast, roasted
  • Cheese, cheddar or mozzarella
  • Kidney beans, cooked
  • Peas, boiled
  • Oatmeal, instant
  • Flounder or sole

What is Dna replication said to be?

Based on how it occurs, it is said to be 'semi-discontinuous' replication.

What is the chemical use to cause polyploidy?

Colchicine is commonly used to induce polyploidy in plants. It disrupts microtubule polymerization, leading to the formation of cells with double the normal chromosome number. This can result in increased genetic variation and potential for breeding new varieties with desirable traits.

Which of these proteins in mammals show only primary and secondary structures?

Collagen and keratin are examples of proteins in mammals that primarily exhibit only primary and secondary structures. Collagen is known for its triple helix structure, while keratin is a fibrous protein that forms alpha-helices and beta-sheets.

What is chemosynthesis and how is it different from photosynthesis?

Chemosynthesis is the process by which organisms use chemical energy to produce food. This is different from photosynthesis, which is the process by which green plants and some other organisms use sunlight to convert carbon dioxide and water into glucose for energy. Chemosynthesis does not require sunlight and can occur in environments where light is not available, such as deep-sea hydrothermal vents.

Does Benedict's solution reacts with proteins?

Benedict's solution reacts with reducing sugars, not proteins. It is commonly used in biochemical tests to detect the presence of reducing sugars such as glucose. Proteins do not typically react with Benedict's solution.

What hormone is the most important stimulus of epiphyseal plate activity?

The growth hormone is the most important stimulus of epiphyseal plate activity, as it is responsible for stimulating the growth of bones during childhood and adolescence. It acts on the epiphyseal plates to promote bone growth and elongation.

Is calcium bentonite clay and di tri octahedral smectite the same?

No, calcium bentonite clay and di tri octahedral smectite are not the same. Calcium bentonite is a type of clay that contains calcium ions and is commonly used in skincare and wellness products. Di tri octahedral smectite refers to a group of crystalline minerals with specific structural properties, and it is sometimes used in industrial applications or as an additive in certain products, but it is not the same as calcium bentonite clay.
