What else can I help you with?
Where do the enzymatic reactions of the Calvin cycle take place?
The enzymatic reactions of the Calvin cycle take place in the stroma of the chloroplasts in plant cells. This is where the enzymes responsible for the fixation of carbon dioxide and the production of sugars are located.
What does a lower substrate concentration signify in enzymatic reactions?
A lower substrate concentration in enzymatic reactions indicates that there is less of the molecule that the enzyme acts upon. This can affect the rate of the reaction, as enzymes require substrates to bind to and convert into products. With lower substrate concentrations, the reaction may proceed more slowly until more substrates are available for the enzyme to work on.
What three enzyme catalysed chemical reactions that happen inside living organisms?
ATP synthase catalyzes the conversion of ADP and inorganic phosphate into ATP. Catalase catalyzes the decomposition of hydrogen peroxide into water and oxygen. DNA polymerase catalyzes the formation of new DNA strands by adding nucleotides to a growing DNA chain during DNA replication.
The dark reactions of photosynthesis are those that?
The dark reactions of photosynthesis, also known as the Calvin cycle, occur in the stroma of the chloroplast and do not require light energy. They involve the conversion of carbon dioxide into glucose through a series of enzymatic reactions. The dark reactions use the products of the light reactions, ATP and NADPH, as sources of energy and reducing power.
Where do the light- independent reactions occur?
light independent reactions take place in thylakiods- more specifically in the thylakiod membranes of chloroplasts.
Is it non enzymatic or enzymatic?
To determine whether a process is non-enzymatic or enzymatic, one must consider the involvement of enzymes. Enzymatic processes rely on specific proteins that act as catalysts to accelerate biochemical reactions, while non-enzymatic processes occur without enzymes, often involving chemical reactions that happen spontaneously or through physical means. If enzymes are present and facilitate the reaction, it is enzymatic; if not, it is non-enzymatic.
Can Minerals act as fatty acids in enzymatic reactions.?
No, minerals cannot act as fatty acids in enzymatic reactions. Fatty acids are specific types of molecules that are necessary for certain enzymatic reactions to occur, while minerals are inorganic elements that serve as cofactors for enzymes but do not function as fatty acids.
Which factors is utilized by cells to regulate enzymatic reactions?
temperature and pH
What is the process involving chemical reactions in an organelle?
Chemical reactions in an organelle occur when molecules are broken down or synthesized, often through enzymatic processes. Substrates bind to specific enzymes within the organelle, leading to the formation of products. These reactions are tightly controlled and regulated to maintain cellular function.
Which type of nucleic acids are capable of catalyzing some types of enzymatic reactions?
Ribozymes, which are RNA molecules with catalytic activity, are capable of catalyzing some types of enzymatic reactions. They can act as enzymes and facilitate various biochemical reactions in cells.
What is the general equation for all enzymatic reactions?
The general equation for all enzymatic reactions is: Substrate + Enzyme → Enzyme-Substrate Complex → Enzyme + Product. Enzymes catalyze reactions by lowering the activation energy required for the reaction to occur, thereby increasing the rate of the reaction.
Are enzymes involved in synthesis reactions only?
No, enzymes can also be involved in breakdown reactions. Enzymes can catalyze both synthesis (anabolic) and breakdown (catabolic) reactions in the body, depending on the specific enzymatic reaction and the needs of the cell or organism.
Where do the enzymatic reactions of the Calvin cycle take place?
The enzymatic reactions of the Calvin cycle take place in the stroma of the chloroplasts in plant cells. This is where the enzymes responsible for the fixation of carbon dioxide and the production of sugars are located.
What is the difference between the nuclear reactions in a nuclear reactor and those in an atomic bomb?
Nuclear reactions in a nuclear reactor are controlled reactions. The reactions in the atomic bomb are not controlled reactions
Do All biochemical pathways have the same number of enzymatic reactions?
No, not all biochemical pathways have the same number of enzymatic reactions. The number of reactions can vary significantly depending on the complexity and purpose of the pathway. For example, simple pathways may involve just a few reactions, while more complex pathways, such as cellular respiration or photosynthesis, can involve many enzymatic steps. Each pathway is uniquely tailored to its specific biological function and the organisms in which it operates.
What is produced with an enzymatic reaction?
Enzymatic reactions produce products by catalyzing chemical reactions within living organisms. Enzymes act as biological catalysts to speed up reactions by lowering the activation energy required for a reaction to occur. These products can be molecules necessary for cellular functions or for the breakdown of substances in the body.
What may inhibit enzymatic reactions EXCEPT?
Enzymatic reactions can be inhibited by factors such as temperature, pH, and the presence of inhibitors that bind to the enzyme or substrate. Additionally, substrate concentration can also affect reaction rates; if substrates are in low supply, it may limit the reaction. However, an increase in enzyme concentration typically does not inhibit enzymatic reactions; instead, it usually enhances the reaction rate, assuming sufficient substrate is available.
