Biochemistry

The optimum temperature and pH of an enzyme vary depending on the enzyme. Generally, enzymes have an optimum temperature around body temperature (37°C) and an optimum pH around neutral (pH 7). However, these values can differ significantly for different enzymes based on their specific structure and function.

Both start with glycolysis... but once you reach pyruvic acid, they're very different. Respiration final product is an inorganic compound (oxygen) whereas fermentation final product is an organic compound (such as lactic acid or ethanol)

The two building blocks of lipids are fatty acids and glycerol. Fatty acids are long hydrocarbon chains while glycerol is a three-carbon alcohol that serves as the backbone for triglycerides.

A tertiary protein structure is the three-dimensional arrangement of a polypeptide chain. An example of a tertiary protein structure is the globular shape of enzymes like catalase or lysozyme. This structure is crucial for the protein's function as it determines the active sites and binding sites.

Regulation of the

cell cycle

prevents cell from multiplying and growing when they are not needed. In abnormal cells, they continue through the cell cycle without crucial stop and

checkpoints

. These checkpoints are important because this is how the cell determines if the phase before was carried out properly. Lots of cancers form because of this. Cell that proliferate through its cycle and continue to grow and grow and grow.

Mitochondria have two [bi-lipid layer] membranes: a smooth and slightly elastic outer membrane and an inner membrane that has [surface area increasing] inward folds called cristae.

Inside the inner compartment is the 'matrix', which is a gel-like phase that contains about 50% protein.

An average apple typically contains about 25-30 grams of carbohydrates, with the majority coming from natural sugars like fructose.

No, allosteric regulation involves molecules binding to a site other than the active site (allosteric site) to either activate or inhibit enzyme activity. This type of regulation can involve activators or inhibitors that induce conformational changes in the enzyme, affecting its activity.

The cell can produce a net gain of 2 ATP molecules from a single molecule of glucose through the process of glycolysis. This occurs during the conversion of glucose to pyruvate.

Maintaining a constant internal temperature and pH values is crucial for the proper functioning of enzymes and metabolic processes within living organisms. Fluctuations in temperature and pH can denature proteins, disrupt biochemical reactions, and ultimately lead to cell dysfunction or death. Consistency in these parameters ensures optimal conditions for biological processes to occur efficiently.

No, amino acids do not lose 3 OH ends. Amino acids have one carboxyl group (COOH) and one amino group (NH2) attached to a central carbon atom. The central carbon atom also has a side chain (R group) attached to it.

Hydrophobic means water fearing tails and hydrophilic means water loving heads

First of all, these terms are involved when you are looking at the cell membrane. The structure of the cell membrane is called a phospholipid bilayer. Which means that the cell membrane is actually made to two layers and not one.

If you take a look at the image, you will see that the little white sphere shaped objects are the hydrophilic heads, and the two little string-like objects attached to the hydophilic heads are the hydrophobic tails. All of the other stuff in the image is all of the extracellular proteins and such. But yes, as the previous answerer said. The hydrophilic heads are on the outer part of the bilayer because they are "water loving". Whereas the hydrophobic tails are on the inner part of the bilayer for two reasons. First, they are hydrophobic or "water fearing" so they will repel water. An example of hydrophobic is oil in water. The oil will form blob-like shapes in the water. Second, the hydrophobic tails also have a somewhat attraction to each other.

"They" could be spraying various things, such as pesticides, herbicides, or even geoengineering substances for weather modification. It is best to research and verify the specific spraying activity in question for accurate information.

In general, they use neither. The terms active and passive transport refer to movement ACROSS cell membranes--from one side to the other. Neurotransmitters are packaged inside membrane and they leave the neuron through exocytosis. They re-enter the neuron through receptor-mediated endocytosis. That means they never really pass THROUGH the membrane.

ATP is the chief energy currency of all cells.

The cell membrane controls what enter and leaves the cell, it also gives the cell shape.

The gases of the environment are important to all living things because they help them in various processes. For instance animals need oxygen for respiration while the plants need carbon dioxide for photosynthesis.

Yes, bacteria use glycolysis to break down glucose into energy in the form of ATP. Glycolysis is a universal metabolic pathway found in nearly all organisms, including bacteria.

Phospholipids have polar head and non-polar tails. Phospholipids help form cell barriers, like the cell membrane.

No, RNA is not the universal energy currency in living cells. Adenosine triphosphate (ATP) is widely recognized as the universal energy carrier in cells, playing a critical role in energy transfer and storage within the cell. RNA, on the other hand, is primarily involved in directing protein synthesis and gene expression.

Excessive production of parathyroid hormone (PTH) can lead to demineralization of bones and increase the risk of spontaneous fractures. This condition is known as hyperparathyroidism.

Tertiary structure in proteins is held together by intermolecular R group interactions, including hydrogen bonding, hydrophobic interactions, ionic interactions, and disulfide bonds. These interactions help stabilize the folding of the protein into its unique three-dimensional shape.
