What else can I help you with?
Why do many spontaneous reactions occur very slowly and theu don't occur instantly?
a. all reactions are endergonicb. many reactions require large inputs of activation energyc. no catalysts are present in body cellsd. there is not enough ATP in body cells
What reversable reactions occur in the container?
There are a couple reversible reactions that occur in the container. For example, one of the reactions is that gas can be reversed to a solid.
Do Most biochemical reactions need help to get started?
Yes, most biochemical reactions require help to get started, typically in the form of enzymes. Enzymes are biological catalysts that lower the activation energy needed for reactions to occur, allowing them to proceed at a faster rate and under milder conditions. Without these enzymes, many biochemical reactions would occur too slowly to sustain life.
How else are nuclear reactions unlike chemical reactions?
In nuclear reactions the atom itself changes while molecules and/or structural organisation of atoms do in chemical and physical changes.
What are true reactions of the Sun?
They are fusion reactions, and The force to get the reactions to occur comes from gravity.
What condition must be present for light independent to occur?
Two condition that must be present for light independent reactions to occur is the presence of CO2 and the presence of ribulose bisphosphate. Two other conditions include the presence of ATP and NADPH and the presence of required enzymes.
What are acidic and basic conditions that occur due to the reactions in the body?
In the body, acidic conditions can occur due to the production of lactic acid during intense exercise or when carbon dioxide levels increase in the blood. Basic conditions can occur when excess bicarbonate is present in the blood, such as during hyperventilation or in cases of kidney dysfunction. The body closely regulates pH levels to maintain a balance between acidity and alkalinity for proper functioning of cells and organs.
Biochemical reactions in the body must occur in what?
Biochemical reactions in the body must occur in a specific order and under controlled conditions in order to maintain the body's functions. Enzymes play a critical role in facilitating these reactions by speeding up their rate without being consumed in the process. Any disruption in the sequence of biochemical reactions or the conditions they occur in can lead to dysfunction and potential health issues.
All but which condition must be present for light-independent reactions to occur?
the plant is exposed to light
True or false The light reactions of photosynthesis can occur only under light conditions and the dark reactions can occur only during the dark hours?
False. The light reactions of photosynthesis require light to convert solar energy into chemical energy, while the dark reactions (Calvin cycle) do not directly rely on light and can occur in both light and dark conditions. However, the dark reactions are indirectly dependent on the products of the light reactions.
What are the conditions necessary for rusting?
The conditions necessary for rusting are water (or water vapour) and air, specifically Oxygen. If one condition is absent and the other is present then rusting would not occur but if both are present then rusting will occur
Why do many spontaneous reactions occur very slowly and theu don't occur instantly?
a. all reactions are endergonicb. many reactions require large inputs of activation energyc. no catalysts are present in body cellsd. there is not enough ATP in body cells
What are the conditions that must be present in order for each process to occur?
poo on bread
What special proteins catalyze chemical reactions that would otherwise require conditions not present inside of cells?
Enzymes are special proteins that catalyze chemical reactions by lowering the activation energy required, allowing reactions to occur at physiological temperatures and pressures inside cells. These biological catalysts are essential for speeding up specific biochemical reactions in living organisms.
Can SN2 and E2 reactions occur simultaneously?
Yes, SN2 and E2 reactions can occur simultaneously in a reaction mixture, especially when both nucleophiles and strong bases are present. This can lead to a mixture of products with different substitution and elimination outcomes.
What are the irreversible reactions of glycolysis and how do they occur under intracellular conditions?
The irreversible reactions of glycolysis are catalyzed by enzymes that only work in one direction. These reactions occur under intracellular conditions when the concentration of reactants and products favors the forward direction of the reaction, making it energetically favorable. This ensures that the glycolytic pathway proceeds efficiently towards the production of energy in the form of ATP.
Why can elements be produced in the sun but not in earths atmosphere?
Elements can be produced in the sun through nuclear fusion reactions that occur due to the intense heat and pressure. These conditions are not present in Earth's atmosphere, which is why elements are not produced there. Earth's atmosphere primarily consists of gases and does not contain the necessary conditions for nuclear fusion to occur.
