What would happen to the human body without enzymes?
To put it simply, a person would not survive. The enzymes allow chemical reactions to occur. Without enzymes, the body would not be able to gain nutrients, flush out toxins, or exhale carbon dioxide.
Biological importance of buffer?
Many chemical reactions are affected by the acidity of the solution in which they occur. In order for a particular reaction to occur or to occur at an appropriate rate, the pH of the reaction medium must be controlled. Such control is provided by buffer solutions, which are solutions that maintain a particular pH. Biochemical reactions are especially sensitive to pH. Most biological molecules contain groups of atoms that may be charged or neutral depending on pH, and whether these groups are charged or neutral has a significant effect on the biological activity of the molecule.
What is cellular enyzmes?
An intracellular enzyme is an enzyme that is inside a cell that must be activated by a specific molecule. Because it is inside the cell, an average signal molecule cannot go through and activate it. Intracellular enzymes are activated by a hydrophobic material such as steroid molecules which can go through the cell membrane and activate the intracellular enzyme.
All cells of an organism are engaged in many different chemical reactions This fact is best supported by the presence in each cell of thousands of different kinds of?
Enzymes. Enzymes are catalysts that facilitate and regulate thousands of different chemical reactions within cells by speeding up these reactions without being consumed in the process. The diversity of enzymes in each cell reflects the wide array of biochemical pathways that cells must carry out to maintain life processes.
What is the importance of water in cells?
most cells and tissues contain large amounts of water- up to 95% in some, with an average of 70-80% water throughout all organisms. molecules must dissolve in water in order to move easily in and between living cells. polar molecules, such as sugar, and ions such as Na+, dissolve in water because of an electric attraction between them and the water molecules. non-polar molecules, such as fats and oils, do not dissolve in water.

What kinds of chemical reations occur inside the body?
Literally there are hundreds of billions of chemical reactions which take place in the human body per second alone. These include how we make heat and energy through respiration of oxygen (O2) and glucose (C6H12O6). There is also how this reaction produces the waste of CO2, and how the blood carries it as carbonic acid to be expelled by the lungs.

Why must the light reactions occur prior to the dark reactions?
The light reactions must occur prior to the dark reactions because they generate the essential energy carriers, ATP and NADPH, needed for the Calvin cycle. These energy-rich molecules are produced when chlorophyll absorbs sunlight, initiating the process of photosynthesis. The dark reactions, or Calvin cycle, rely on the ATP and NADPH from the light reactions to convert carbon dioxide into glucose. Without the light reactions, the energy and reducing power required for the dark reactions would not be available.

Summary of waste disposal issue including an explanation of some of the chemical reactions that must occur to break down the waste the rates at which they occur and the obstacles inhibit them?
FUNGI?????????
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.
What are some of the chemical reactions that must occur to break down waste and how fast do they occur?
Chemical reactions such as hydrolysis, acidogenesis, acetogenesis, and methanogenesis are involved in breaking down waste in biological processes like anaerobic digestion. The speed at which these reactions occur can vary based on factors like temperature, pH, and the specific waste composition, but generally, biodegradation processes can take days to several weeks to complete.
What is an another name for exothermic and for endothermic reactions?
it is a Many chemical reactions release energy in the form of heat, light, or sound. These are exothermic reactions. Exothermic reactions may occur spontaneously and result in higher randomness or entropy (ΔS > 0) of the system. They are denoted by a negative heat flow (heat is lost to the surroundings) and decrease in enthalpy (ΔH < 0). In the lab, exothermic reactions produce heat or may even be explosive. There are other chemical reactions that must absorb energy in order to proceed. These are endothermic reactions. Endothermic reactions cannot occur spontaneously. Work must be done in order to get these reactions to occur. When endothermic reactions absorb energy, a temperature drop is measured during the reaction. Endothermic reactions are characterized by positive heat flow (into the reaction) and an increase in enthalpy (+ΔH).
What must occur for a solution to form?
The correct answer is as follows: One Substance Must Dissolve In Another.
