Biochemistry

The term "protoplasm" was coined by Czech physiologist Jan Evangelista Purkyně in 1839, but the concept of protoplasm as the living substance within cells was a collective discovery made by several scientists in the early 19th century, including Matthias Schleiden and Theodor Schwann. They observed that cells were composed of this material that exhibited properties of life.

To locate enzyme immunoassays in the CPT manual, you would search for "enzyme immunoassay" or the specific codes associated with the type of test you are looking for in the index. You can also check under the section related to laboratory tests or immunoassays for additional information.

Anaerobic reactions, like fermentation or anaerobic respiration, occur in the absence of oxygen and release energy by breaking down glucose or other molecules into simpler compounds. These reactions are important for organisms that live in environments with low oxygen levels.

A zygote is single cell which is formed immediately after fertilization . IT then converts to morula followed by blastula (ZYGOTE DIVIDED INTO 16-32 cells) WHICH GETS IMPLANTED IN THE UTERINE WALL . IT THEN DIVIDES TO FORM EMBRYO WHICH AFTER 9 MONTHS IS RECOVERED FROM THE MOTHER

First, not every Enzyme needs vitmains for function but a lot. Vitamins serve as special components in an enzyme or a protein and fullfill functions that cannot be done by simple polypeptides.

Bacteria can develop resistance to antibiotics through genetic mutations or by acquiring resistance genes from other bacteria. Over time, the resistant bacteria population can grow, making the antibiotics less effective in treating infections caused by those bacteria. This can lead to treatment failure and the need for more powerful antibiotics.

The genetic code is degenerate, meaning that multiple codons (sequences of 3 nitrogen bases) can code for the same amino acid. This redundancy allows for 4 nitrogen bases to encode for 20 different amino acids. By combining these amino acids in various sequences, thousands of different proteins can be synthesized.

The three main elements found in macromolecules are carbon, hydrogen, and oxygen. These elements are essential for building the complex structures of biological macromolecules like proteins, carbohydrates, and lipids. Additional elements like nitrogen, sulfur, and phosphorus can also be present in certain macromolecules.

The correct pairings of nucleotides in RNA are adenine (A) with uracil (U), and guanine (G) with cytosine (C).

Yes, lysosomes play a crucial role in autophagy. They fuse with autophagosomes, which are vesicles that contain cellular debris or organelles targeted for degradation. Once fused, lysosomal enzymes break down the contents of the autophagosome, recycling essential molecules for the cell.

Eukaryotic cells are cells with a nucleus and organelles, which are found in both plants and animals. Some common organelles in eukaryotic cells include the mitochondria, endoplasmic reticulum, and Golgi apparatus. These organelles support various functions such as energy production, protein synthesis, and cellular transport.

the substance that an enzyme acts upon is subtrate

The structure with a "H" atom in place of an "OH" group represents deoxyribose in the DNA backbone. This is because deoxyribose lacks an oxygen atom at the 2' position, distinguishing it from ribose in RNA.

3 milligrams of protein. 6 milligrams of iron.

Enzymes are catalysts. They help lower the activation energy of reactions and increase the rate of the reaction. Without the help of enzymes, the biochemical reactions in the body would take so long that it would kill the person.

Growth hormone is primarily responsible for stimulating muscle synthesis and recovery during sleep. It plays a key role in repairing and building muscle tissue, promoting overall muscle growth, and enhancing recovery from physical activity. Growth hormone levels are typically highest during deep sleep stages, making quality sleep essential for muscle recovery and development.

The levels of organization in multicellular organisms typically include cells, tissues, organs, and organ systems. Cells group together to form tissues, tissues work together to create organs, and organs collaborate to form organ systems that function together to support the organism's overall health and survival.

A logic connective is a symbol or word used to connect different parts of a logical statement. Common logic connectives include "and," "or," "not," and "if-then." They help to express relationships between propositions in logic.

RNA polymerase is anabolic, meaning it helps build RNA molecules from nucleotide building blocks by linking them together in a specific sequence. It does not typically break down molecules for energy or raw materials, which is characteristic of catabolic processes.

In biochemistry, an endpoint assay measures the final amount of a product formed or substrate remaining after a reaction has stopped, providing a single data point. A kinetic assay, on the other hand, measures the rate of a reaction by recording multiple data points over time. Kinetic assays provide additional information about reaction mechanisms, enzyme activity, and inhibitor kinetics compared to endpoint assays.

Recycling plastic and paper products can benefit wildlife by reducing the amount of waste that ends up in their habitats. Wildlife can mistake plastic for food, leading to ingestion and potential harm. By recycling, we help protect wildlife by minimizing their exposure to harmful waste materials.

A micropipette measures and transfer small volumes of liquid in the microliter (μL) or milliliter (mL) range with high accuracy and precision. It is commonly used in biological and chemical laboratories for tasks such as measuring out reagents, samples, or standards for analysis.

Phosphorus is important in cellular respiration because it is a key component of ATP (adenosine triphosphate), which is the primary energy currency in cells. During cellular respiration, ATP is produced through processes like glycolysis, the citric acid cycle, and oxidative phosphorylation, where phosphorus is essential for the synthesis and transfer of energy within the cell.

No, yet it is a crucial and complex Part of the Factory that processes the raw materials.

While Chlorophyll is required for photosynthesis, it is not used up in the process of photosynthesis and none of its parts are used in the chemical reactions of photosynthesis. Only the energy it absorbs from the Sun is used in photosynthesis.
