Answer:
A Chemical Energy
Explanation:
Chemical energy, Energy stored in the bonds of chemical compounds. Chemical energy may be released during a chemical reaction, often in the form of heat.
Answer: c) They are reversible inhibitors
Explanation: B-lactam antibiotics are not are reversible inhibitors. reversible inhibitors are inhibitors which the allow enzymes they inhibit to start working again, as there is no perman effects on the enzymes ( there is no change to the shape of it active site.). They can sometimes appear as competitive, non-competitive or uncompetitive.
Answer:
Carbohydrates and lipids are similar in that they are both sources of energy but they are different in the amount of energy they produce.
Explanation:
Carbohydrate and lipids are similar in the sense that both of them are parts of foods consumed by humans and the two marcro molecules are good sources of energy for the body cells. The carbohydrate has to be broken down to glucose before it can be absorbed by the body cells. This is because glucose is the only energy source that the body cells can use. The lipid has to be converted to glucose through biochemical reactions such as gluconeogenesis before the cells can use it.
The basic difference between the two energy sources is that the amount of energy that they supply is quite different. Lipid contains more energy than carbohydrate; carbohydrate can only supply about one-quarter of the energy that lipid can supply.
I would say D, but I could be wrong
Answer:
B. Corundum
Explanation:
Using the Mohs scale of hardness, the mineral has a hardness greater than 6.5 (Steel nail) but less than 8.5 (Drill bit). The corundum has a hardness of 9.0, which means it cannot be scratched by a drill bit, but all the other choices have a hardness scale less than 6.5 but the mineral was not scratched by the nail. So the best answer would be B.
