Answer and Explanation:
Protein is one of the most important molecules in our organism, being present in the composition of all elements, in addition to participating in several metabolic processes. This importance creates the need to study this molecule, however, to study it it is necessary to know the composition chemistry and the levels of structure it presents.
The chemical composition of proteins is related to amino acids, since protein is formed by them. In this case, we can say that the proteins have the same composition as the amino acids containing carboxylic acid and different amino groups, which is what determines the name and function of the amino acid.
In addition to chemical composition, the structure levels of proteins are extremely important, as they only function at a specific structural level. As for these levels, proteins can have a primary structure (there are more than two amino acids organized in a linear row), a secondary structure (when the primary structure turns into a helix species), a tertiary structure (formed by a more intense folding of the secondary structure providing the appearance of helices and leaves) and quarternary structure (when several tertiary structures are joined, allowing folding at the three-dimensional level. This is the functional structure of the protein).
What does lemon juice, snake venom and cyanide have in common?
Answer:
enzymes are protein molecules that act as catalysts, speeding up chemical reactions without themselves getting used up. Each enzyme will only speed up a specific reaction, for example, catalase will speed up the decomposition of hydrogen peroxide into water and oxygen but it will not speed up the breakdown of starch into glucose. Enzymes (e.g. catalase) have active sites with specific shapes that bind to the substrate molecule (e.g. hydrogen peroxide) forming an enzyme-substrate complex. The enzyme-substrate complex then breaks down into the enzyme and product, allowing the enzyme to go on and react with another substrate molecule. Temperature and pH affect enzyme function because they can change the shape of the enzyme’s active site, preventing it from binding to the substrate, just as a broken lock will no longer fit the key. When the shape of an enzyme changes we call this denaturation. Any factor that increases the frequency of collisions between enzymes and substrates (increasing concentration, surface area or temperature) will increase the rate of reaction.

Explanation:
the sequence of _____ in a dna molecule determines the protein that will be produced
Answer: gene
Explanation: The sequence of bases in a DNA molecule can determine the order of amino acids in a protein molecule. Groups of three bases called triplets represent different amino acids. This is the basis of the genetic code . A sequence of bases (genetic information) on DNA that codes for a protein is called a gene .

Hope it help you
Stayhomestaysafe
Plz mark my answer brainliest✍️✍️
Explanation:
Arrows have come to represent protection and defence from any evil that can come to you. Sustenance – Arrows were used to fight enemies and to hunt food, two important aspects of sustaining life. As a result, an arrow symbolizes maintaining and protecting life.
REAL NAME - SHRESTH DUBEY
The arrows in a food chain represent the flow of energy or the transfer of nutrients between different organisms in an ecosystem.
They indicate the direction of energy transfer, showing which organism is being consumed by another. The arrow always points from the organism being consumed (prey) to the organism consuming it (predator).
The primary producers, such as plants or algae, are at the beginning of the food chain and transfer energy to herbivores (primary consumers), which are then consumed by carnivores (secondary consumers) or other higher-level consumers.
The arrows help depict the interconnectedness and energy flow within an ecosystem, illustrating the feeding relationships between organisms.

The correct answer is D i.e. krebs cycle occurs in mitochondria.
what is mitochondria?
Mitochondria are membrane-bound cell organelles (mitochondrion, singular) that generate most of the chemical energy needed to power the cell's biochemical reactions. Chemical energy produced by the mitochondria is stored in a small molecule called adenosine triphosphate (ATP)
what is krebs cycle?
The tricarboxylic acid (TCA) cycle, also known as the Krebs or citric acid cycle, is the main source of energy for cells and an important part of aerobic respiration. The cycle harnesses the available chemical energy of acetyl coenzyme A (acetyl CoA) into the reducing power of nicotinamide adenine dinucleotide (NADH).

What is the name of a double layer of phospholipids (called lipid bilayer)?
The name of a double layer of phospholipids is called a lipid bilayer.
The lipid bilayer is a fundamental component of cell membranes and plays a crucial role in maintaining the integrity and function of the cell. It consists of two layers of phospholipids arranged in such a way that the hydrophobic (water-repellent) fatty acid tails are sandwiched between the hydrophilic (water-loving) phosphate heads.
This arrangement creates a barrier that controls the passage of substances into and out of the cell, allowing for selective permeability. The lipid bilayer also houses various proteins, cholesterol molecules, and other components that contribute to the overall structure and function of the cell membrane.
Thus, the correct option is lipid bilayer.

find cos A if sin A=3/5
Explanation:
for sin we divide the opposite by the hypotenuse
and for cos we require the adjacent divided by hypotenuse

Detailed information about the processes and tectonic plate interactions that are causing the volcanos to occur. Include an explanation of convection currents.
Answer:
Tectonic plates recurring over and over again cause a rupture in the Earth's crust. This agitates the magma in volcanoes, causing the volcano to erupt.
Explanation:
Answer:
These tectonic plates rest upon the convecting mantle, which causes them to move. The movements of these plates can account for noticeable geologic events such as earthquakes, volcanic eruptions, and more subtle yet sublime events, like the building of mountains.

Explanation:
NASA has discovered a new planet in a distant solar system. On this new planet, they have found a mysterious green slime. The green slime only grows at certain temperatures and under certain moisture levels. Scientists found that if they put the green slime in a freezer, it would shrink itself to maintain an internal temperature of 75°. They also found that the green slime has specialized pumps to pump out water if it gets too wet. As of yet, none of the green slime samples have reproduced, but they do appear to be growing very slowly. When looking at the green slime under the microscope, scientists can see smaller structures filled with green slime and tiny pumps. What are some reasons the green slime may be considered a living organism? What are some reasons the green slime may not be considered a living organism? Do you think the green slime is alive? Why or why not? *
Answer: The following assumptions can be made for the green slime.
Explanation:
1. The green slime has many characteristics, which indicates that these are adaptations which were used by the slime to survive. It uses pump to expel out excess water, and in freezing it can shrink itself to maintain its temperature. Thus these characteristics indicates that the green slime is living.
2. The green slime did not reproduced. This indicates that the slime was not living.
3. The slime was living because it had characteristics which enable it to survive like other living organisms.
