Answer:
Cellular respiration takes place in both the cytosol and mitochondria of cells.
Explanation:
The energy produced by the mitochondria is stored as potential energy in molecules called adenosine triphosphate (ATP). The main chemical produced in cellular respiration is ATP.
Reducing calorie intake is insufficient for a person to loose weight.
If some were to reduce calories, it would cause your stomach to produce more fat cells. It is like you are starving yourself and your stomachs way to save you if producing more fat cells.
Answer:
All the given statements are correct except b.
Antimicrobial resistance (AMR) refers to the ability of a microorganism to grow in the presence of drug or a chemical that would normally limit its growth or kill it.
It makes it difficult for the existing drugs to eliminate the infection as they become less effective against the microbe.
There are five major mechanisms by which a microbe attains resistance against antimicrobial chemical or drug:
- Drug modification or inactivation: A microbial enzyme inactivates the antimicrobial agent. For example, few bacteria produce β-lactamases which provide multi-resistance against β-lactam antibiotics such as penicillin, cephalosporin etc.
- Alteration or modification of target site: An altered target site prevents the antimicrobial agent from binding to its target. For example, alteration of penicillin binding protein (PBP) in Methicillin-resistant <em>Staphylococcus aureus </em>(MRSA).
- Alteration of metabolic pathway: The microbe uses an alternative pathway to circumvent the blocked pathway. For example, sulfonamides-resistant bacteria started using preformed folic acid in place of para-aminobenzoic acid (PABA).
- Decreased drug accumulation: Microbial efflux pumps remove the antimicrobial agent (before it could do any damage) by pumping it out of the cell.
- Decrease in cell permeability: The permeability of the microbial envelope to the antimicrobial agent is decreased
True
Explanation:
The water molecules move from areas of high concentration to areas of low concentration to make an equivalent between the two.
I hope this helps at least a little :D
