Biochemistry

The building blocks of the enzyme catalase are amino acids. These amino acids are arranged in a specific sequence to form the catalase protein, which catalyzes the breakdown of hydrogen peroxide into water and oxygen.

Cyclin-dependent kinases (CDKs) are a type of molecule that control the cell cycle by regulating the progression of cells through different phases. These enzymes work in conjunction with cyclins, which are regulatory proteins that bind to CDKs to activate their kinase function. The activity of CDK-cyclin complexes helps to coordinate the events of the cell cycle.

Bacteria can move using flagella, which are whip-like appendages that spin and propel the bacteria forward. Some bacteria can also move using pili or by secreting slime to glide along surfaces. Additionally, bacteria can move in response to stimuli such as light, temperature, or chemical signals.

The mosaic quality of the cell membrane is due to the presence of various components such as phospholipids, cholesterol, proteins, and glycolipids. These components are arranged in a dynamic and fluid manner, creating a mosaic pattern that allows for flexibility and functionality of the cell membrane. Additionally, the diverse composition of these components helps in maintaining the structural integrity of the membrane.

Foods that supply carbs, proteins and lipids include tofu. Tofu is an even better source of protein that is a good way for vegetarians to get what they need. It also is high in certain lipids, such as potassium. Salmon also gives proteins & lipids.

Glucose is the monosaccharide present in all three disaccharides: sucrose (glucose + fructose), lactose (glucose + galactose), and maltose (glucose + glucose).

when sucrase acts on sucrose it produces fructose and glucose they are both monosaccharides (simple sugars) mono=one saccharide=sugar glucose is nessacary in the making of Adenosine tri phosphate ATP and adenosine diphosphat ADP. ATP is the chemical formulae for energy.

Yes, cycloalkynes are cyclic hydrocarbons with a triple bond. However, they are less stable than cycloalkenes due to angle strain in the ring caused by the presence of the triple bond.

every enzyme has specific optimum temperatures and pH.

1. The pH is very specific even a minor change of .5 will cause the enzyme to denature.

2. The temperature is less specific all enzymes will work below the optimum temperature but the reaction will be slower. Above the optimum temperature the enzyme will denature.

Note the optimum temperature of the human body is around 37.5 degrees C and the optimum pH is around 7.3.

Name of this enzyme is Maltese. It is present in the brush border of the lining of small intestine.

"Tapping" is a procedure in which a powder is placed into a graduated cylinder which is then tapped to compress the sample before its volume is measured. This reduces the amount of air trapped in the material. "Theoretical" is a method of determining the density of a mineral from the volume of a single cell.

Other sugars do enter into glycolysis such as fructose, galactose and mannose. Fructose can directly enter into glycolysis while the other two is converted to a glucose intermediate molecule because it can produce the two triose phophate molecules (DHAP and G3P) which are needed to generate energy from the reactions (ATP) and pyruvate.

Equilibrium constants are essential to answering many thermodynamic questions and to figuring out how a chemical is gonna behave in a solution.

On a routine basis -- meaning someone working in a lab -- you need equilibrium constants to make buffers (henderson-hasselbalch).

The head of a phospholipid can be described as hydrophilic, meaning that it is attracted to water. This portion of the molecule tends to interact with water molecules, while the tail portion of a phospholipid is hydrophobic and repels water.

The N-terminal signal peptide is recognised by SRP (signal recognition particle). SRP directs the peptide to translocons on the membrane of the rough endoplasmic reticulum, usually during translation (co-translational). The translocon is responsible for the transport of the protein into the endoplasmic reticulum, from which it will either be secreted or sent to organelles such as the mitochondria, chloroplasts, endosome, lysomome and peroxisome. These organelles require that proteins go through the endoplasmic reticulum as the proteins are incorporated into the organelles through vesicular transport, as they do not have their own uptake methods.

Proteins destined for the nucleus are not sent through the endoplasmic reticulum, as the method of transport into the nucleus is not vesicular. Instead, the nucleus has its own pores capable of translocating proteins into the nucleus.

Small objects can pass through these nuclear pores by passive transport, but anything bigger than 40kDa requires a special mechanism. Proteins destined for the nucelus have a nuclear-localisation signal (NLS) instead of the N-terminal signal peptide. The NLS is a seven residue sequence of basic amino acids at the C-terminus.

Extracellular fluid refers to all the fluids outside of our cells in our bodies. The term for the fluid inside of our cells is intracellular and refers to the cytoplasm. The fluids outside of our cells is referred to as extracellular because they are outside the cells.

There are two different categories of extracellular fluids. The first is interstitial fluid which is the fluid that is in between our cells and tissues, and the other is plasma, which is found in our blood. The reason why this is called the internal environment is because this is the environment that our cells in our bodies live in.

So the internal environment in our body is really the "sea" of fluids outside our cells that keeps them alive, hence their environment. This is much like the things outside of our bodies that are our environment that keeps us alive.

The solubility of oxygen in water decreases as water temperature increases, making it harder for aquatic animals to obtain enough oxygen to support their metabolism in deep, warmer waters where oxygen concentrations may be naturally lower. This can create oxygen-depleted zones that limit the distribution and survival of marine organisms.

You might be referring to salivary amylase. Maltase is an enzyme produced by duodenum that breaks down the sugar maltose into glucose. Salivary amylase is an enzyme located in your saliva (there is also pancreatic amylase found in the pancreas). This enzyme breaks down carbohydrates (more specifically starch) which then can be absorbed in the small intestine.

By heating the milk solution up to 40 degrees, you are denaturing the protein. So that when you add up the acetic acid with the solution, the acetic acid will be able to bind with the denatured protein, making the environment necessary for casein coagulation.

Yes, the absorbance maximum (Amax) of bromophenol blue does vary with concentration. As the concentration of bromophenol blue increases, the Amax shifts from its initial value. This change in Amax can be used to determine the concentration of bromophenol blue in a solution through spectrophotometric analysis.

Endocrine glands produce hormones that are distributed through the bloodstream. These glands, such as the pituitary gland, thyroid gland, and adrenal glands, regulate various functions in the body by releasing hormones into the blood to target specific organs and tissues.

When a metal has electrons that are not tightly held together by any one atom in the crystalline structure it is generally a good conductor of electricity. This is because as current moves into the metal electrons are free to flow and move through the metal. This is the definition of a conductor.

No, dextrin and dextran are not the same. Dextrin is a short-chain carbohydrate produced from starch, while dextran is a long-chain carbohydrate produced by bacteria during fermentation. They differ in structure, properties, and uses.

It is highly unlikely for two people to have the exact same RFLP banding pattern due to the vast genetic variability among individuals. RFLP analysis is based on variations in DNA sequences, making it improbable for two unrelated individuals to have identical patterns.
