What is the relationship between a fuel cell and a primary cell?
Both fuel cells and primary cells are devices that convert chemical energy into electrical energy. The main difference is that primary cells use stored chemical energy in the form of a non-rechargeable chemical reaction, while fuel cells continuously receive fuel and an oxidizing agent to generate electricity through a controlled chemical reaction.
Chemical reactions drive all of the activities within what?
Chemical reactions drive all of the activities within living cells.
Which best describes the role of enzymes in chemical reactions?
Enzymes are biological catalysts that speed up chemical reactions by lowering the activation energy required for the reaction to occur. They do this by bringing together specific molecules in the correct orientation to promote the reaction. Enzymes are highly specific to their substrates and play a crucial role in regulating metabolism within cells.
Are most chemical reactions at equilibrium in living cells?
No, most chemical reactions in living cells are not at equilibrium. Cells maintain a dynamic balance, constantly adjusting reaction rates to respond to changing conditions and maintain homeostasis. Equilibrium is rare in living systems due to the constant flux of molecules and energy.
What is the main product of the chemical reaction that your cells need?
The main product of cellular respiration, the chemical reaction your cells need, is adenosine triphosphate (ATP). ATP is the primary energy source for cellular processes and is produced through the breakdown of glucose and other nutrients in the presence of oxygen.
What are the chemical changes in the cells of an organism called?
nuclear reaction
What is the term for an organism that can make its own food by carrying out a chemical reaction inside of its cells?
Autotrophs
Chemical reaction of radon poisoning?
No chemical reaction, but irradiation of the cells.
What are the factors of growth in cells?
Cell potential depends on the chemical used, concentration,
Cells of an organism perform the following chemical reaction 6 CO2 plus 6 H2O plus and rarr C6H12O6 plus 6 O2 To which organism do these cells most likely belong?
These cells most likely belong to a plant, as the chemical reaction represents photosynthesis, a process unique to plants where carbon dioxide and water are converted into glucose and oxygen in the presence of light.
When something does this it gives out light?
Bioluminescence is the emission of light by living organisms. This natural phenomenon occurs in various marine species, plants, and even insects. The light is typically produced through a chemical reaction within the organism's cells.
How do cells know to develop within a multicellular organism?
They receive instructions in their DNA.
What chemical reaction is taking place in the green organelles in plant cells?
This chemical reaction is called photosynthesis.
What is the special ability of a noctiluca called?
The special ability of a noctiluca is called bioluminescence. This allows the organism to produce and emit light through a chemical reaction within its cells, typically used for communication, attracting prey, or avoiding predators.
Broad term that covers all chemical reactions within the body cells?
Metabolism is the broad term that covers all chemical reactions within the cells of the body. It includes processes such as breaking down molecules to obtain energy (catabolism) and building up molecules for growth and repair (anabolism).
What is a biological catalist?
A biological catalyst is a substance, typically a protein (such as an enzyme), that increases the rate of a chemical reaction within a living organism. Biological catalysts work by lowering the activation energy required for a reaction to occur, thus speeding up the process. This enables essential biological processes to occur efficiently in cells and organisms.
Is chemical reaction the same as metabolic reaction?
In a way, yes. Metabolic reactions are capable of chemical reactions. Specialized cells, such as nerve, muscle, or blood cells, carry out distinctive chemical reactions. However, all cells perform certain basic reactions, such as buildup and breakdown of carbohydrates, lipids, proteins, and nucleic acids. These reactions include hundreds of specific chemical changes that occur rapidly - yet in a coordinated fashion - thanks to enzymes.
