You need vitamin A for healthy eyesight and skin.

Oestrogen, or estrogen, is the primary hormone of the female reproductive system. It is responsible for menstruation, making reproduction possible by thickening the lining of the uterus, and is partly responsible for the development of breasts.

The fidelity of replication is backed by corrective mechanisms to ensure that said replication is a perfect as possible and the same protein structure is being coded for in the daughter cells. Naturally, no process is perfect and mutations will happen, but they are, generally, neutral.

Enzymes are biological catalysts. This means they break down substances without being changed themselves. This is why they can be used over and over again. Enzymes are made from amino acids joined together by different bonds, one of the type of bonds being hydrogen bonds. As enzymes have hydrogen bonds it means they are sensitive to pH and temperature. A temperature too low will mean that the molecules (substrate) which should fit to an area on the enzyme called the active site cannot do so as hydrogen bonds are stronger in colder conditions. (Enzymes change slightly as the substrate fits on to it) This would mean that the enzyme is less able to change shape slightly because the stronger hydrogen bonds make the enzyme less flexible. Temperatures which are too high for the enzyme (if they exceed the perfect temperature, called the optimum temperature, of the enzyme) denature the enzymes, meaning that they are unable to catalyse chemical reactions, this is due to the high temperature causing the hydrogen bonds which bond the amino acids together to beak, causing the enzymes active site to change shape, meaning that the substrate can no longer fit into the active site meaning that the rate of reaction of the chemical reaction is lower. There is a point when the hydrogen bonds, once broken, are no longer able to re-bond, meaning the enzyme could never "re-nature". This is very bad if the chemical reaction is necessary. If the pH which the enzyme is exposed to is not its optimum the rate of reaction will be slower as the pH changes the molecular shape of the enzyme, and can have an effect on the intermolecular forces of the Hydrogen bonds (it can weaken or strengthen them)

Carbohydrates are found in various foods such as grains (like rice, pasta, bread), fruits, vegetables, legumes, and dairy products. They are also found in processed foods like sweets and sugary beverages.

yes and a few more but having the same basic atoms doesnt mean its the same thing.

lipids contain carbon and hydrogen

carbohydarates contian carbon and hydrogen as well but they also contain oxygen

ratios of the number of certain atoms in them are differnet

Glucose is the primary source of energy for living organisms. It is readily broken down during cellular respiration to produce ATP, the energy currency used by cells for various processes. Additionally, glucose is a key component in the synthesis of other important molecules in the body.

Synthesis refers to the process of combining different elements or ideas to create a new whole. It involves bringing together distinct sources of information or perspectives to develop a cohesive understanding or perspective on a topic. In academic writing, synthesis often involves analyzing multiple sources to produce a new thesis or argument.

The sequence of nucleotide bases, which are adenine (A), thymine (T), cytosine (C), and guanine (G), determines the unique genetic information in each DNA molecule. Variations in this sequence result in different genes and ultimately lead to the diversity observed in living organisms. Additionally, differences in the length or structure of a DNA molecule can also distinguish one from another.

1 amu (atomic mass unit) is a unit of mass equal to one twelfth of the mass of a carbon-12 atom. It is used to express the mass of atomic and subatomic particles.

Enzymes catalyze reactions by lowering the activation energy needed without themselves being used up in the process. Without catalysts such as enzymes, some chemical metabolic reactions would take forever to happen or not happen at all.

a specific enzyme usually catalyzes only one kind of chemical reaction

Vitamin C can act as an antioxidant in plants, helping to protect them from oxidative stress and damage. While plants do not require vitamins like animals do, they can benefit from the presence of certain vitamins in their environment to support their growth and defense mechanisms.

During respiration, carbon dioxide gas is released as a byproduct of cellular metabolism. This occurs during the process of breaking down glucose to produce energy in the form of ATP. Carbon dioxide is then exhaled out of the body through the lungs when we breathe.

ADP (Automatic Data Processing) is a company that provides human resources, payroll, and benefits administration solutions for businesses. They offer services such as payroll processing, time and attendance tracking, HR management, and employee benefits management. ADP helps businesses streamline their administrative processes, improve efficiency, and comply with regulations.

The structure of DNA was described by James Watson and Francis Crick in 1953.

One example of an exergonic redox reaction in mitochondria is the electron transport chain, which occurs during cellular respiration. In this process, electrons are transferred between protein complexes in the inner mitochondrial membrane, releasing energy that is used to generate ATP.

The chemical formula for phosphoric acid is H3PO4.

There are two types of amylase enzymes. Salivary amylase is known as ptyalin; act upon carbohydrates in the mouth. Ptyalin begins polysaccharide digestion in the mouth; the process is completed in the small intestine by the pancreatic amylase, sometimes called amylopsin.

Chemically they are all inert - they do not combine with any other element.

Physically they vary in many ways due to their differing atomic weights. Features such as melting and boiling points, specific heat, density etc. will all be different.

Some challenges in determining the Michaelis constant (Km) include experimental variability, the presence of enzyme inhibitors or activators, substrate inhibition, and inaccuracies in substrate concentration measurements. Additionally, Km values can be influenced by factors such as enzyme purity, substrate specificity, and reaction conditions, making precise determination difficult.

When hydrogen atoms in a compound behave like exposed protons, they are typically found in a very acidic environment where they can easily donate a proton. In such circumstances, the hydrogen atoms are often attached to electronegative elements like oxygen, nitrogen, or sulfur, which stabilize the resulting proton by delocalizing the charge. This behavior is commonly observed in compounds with functional groups like hydroxyl (-OH), amino (-NH2), or thiol (-SH).

Non-oxidative glycolysis is reliable for producing ATP quickly during intense exercise or quick bursts of energy when oxygen is limited or unavailable. It allows cells to generate energy anaerobically by breaking down glucose without needing oxygen. This process is not as efficient as oxidative glycolysis in terms of ATP production, but it can sustain energy production in emergency situations.

I believe you are refering to a diatomic molecule- although it doesn't really matter whether or not it has bonded yet.
