How does the collision theory work?
The collision theory explains that for a reaction to occur, reactant molecules must collide with sufficient energy and proper orientation. These collisions lead to the formation of an activated complex, which then proceeds to form products. Increasing the frequency and energy of collisions can enhance the reaction rate.
The synthesis of complex molecules from simpler ones with the input of energy is called?
The synthesis of complex molecules from simpler ones with the input of energy is called anabolic reactions. These reactions involve building up molecules and require energy input to form bonds between molecules.
What happens to wood when it burns and why does it undergo such a transformation?
When wood burns, it undergoes a chemical reaction called combustion. The heat from the fire breaks down the wood's complex molecules, releasing carbon dioxide and water vapor as byproducts. This transformation occurs because the heat provides the energy needed to break the bonds holding the wood's molecules together, allowing them to rearrange into simpler compounds.
Controls movement in and out of the nucleus?
The nuclear pore complex controls the movement of molecules in and out of the nucleus. It acts as a selective barrier, allowing only specific molecules to pass through the nuclear envelope. Signals on molecules regulate their transport through the nuclear pores.
What chemical reaction breaks complex molecules down into small molecules?
Catabolism
What is composed of a light-harvesting complex and an electron transport system?
A photosystem is composed of a light-harvesting complex and an electron transport system. The light-harvesting complex captures light energy and transfers it to the reaction center, where electrons are excited and transferred through the electron transport system to generate ATP and NADPH during photosynthesis.
What is the main role of pigment molecules within the antenna or light harvesting complex?
The light-harvesting (or antenna) complex of plants is an array of protein and chlorophyll molecules embedded in the thylakoid membrane which transfer light energy to one chlorophyll a molecule at the reaction center of a photosystem.
How does the light harvesting complex contribute to the process of photosynthesis in plants?
The light harvesting complex in plants helps to absorb light energy and transfer it to the reaction center of photosystems, where it is used to drive the process of photosynthesis. This complex consists of pigments that capture light energy and pass it along to the reaction center, where it is converted into chemical energy to produce glucose and oxygen.
What term is specific to a reaction in which simple compounds are combined into more complex molecules?
The term specific to a reaction where simple compounds are combined into more complex molecules is "synthesis reaction." This type of chemical reaction involves the formation of a new, more complex compound by combining simpler reactants.
What reaction makes complex molecules?
poo and a toilet that stinks badly
What pigment molecules absorb a photon and pass the energy to the reaction-center complex?
chlorophyll
Antennalike energy-harvesting unit in a thylakoid?
Antenna pigments, chlorophyll a, chlorophyll b, and carotenoids, that are light harvesting antennas in the thylakoid. After the antenna pigments absorb light energy and transformed as chemical energy then transfered to the reaction center complex.
Is a condensation reaction an anabolic reaction?
Yes, a condensation reaction is an anabolic reaction. It involves the formation of larger molecules from smaller ones by the removal of a water molecule. This process is common in the synthesis of complex molecules like proteins and carbohydrates.
How does orientation and the activated complex affect a reaction?
Orientation affects the likelihood of successful collision between reactant molecules, increasing the chance of forming the activated complex. The activated complex is a high-energy, unstable intermediate state in a reaction, which is crucial for the reaction to proceed and for products to be formed. The orientation of molecules influences how effectively they can overcome the activation energy barrier to form the activated complex and progress to product formation.
What is the reaction o copper and ammonia?
When copper metal reacts with ammonia, it forms a deep blue complex called tetraamminecopper(II) complex. This reaction involves the displacement of water molecules in the copper sulfate solution by ammonia molecules to form the complex. The blue color is due to the absorption of specific wavelengths of light by the complex.
What is an enzyme product complex?
An enzyme-substrate complex is formed when an enzyme binds to its substrate molecules. This temporary complex allows the enzyme to catalyze a specific chemical reaction by lowering the activation energy required for the reaction to occur. Once the reaction is complete, the products are released and the enzyme is free to catalyze another reaction.
