enzymes are proteins that speeds up the rate of chemical reaction in a living organism . An enzyme acts as catalyst for specific chemical reaction, converting a specific sets of reactants called substrates into specific products with out enzymes life would not be exist
Explanation:
Enzymes are identified to catalyze more than 5,000 biochemical reaction types. Most enzymes are proteins, although a few are catalytic RNA molecules. Enzymes' specificity appears in their unusual three-dimensional structures. Like all enzymes, enzymes improve the reaction rate by decreasing its activation potential.
Answer:
Fat molecules contain more energy-containing bonds than simple sugars.
Explanation:
Lipids are a large group of mostly non-polar hydrophobic hydrocarbons. They include fats and oils, waxes, phospholipids and steroids. They serve many functions in living organisms such as energy storage molecules, information molecules, insulation against cold in some animals etc.
From the information provided above, lipids have 9 kilocalories per gram, 100,000 kilocalories of energy storage, and 30 to 40 days of life support time. When energy provided per gram by lipids is compared with that of either glucose or glycogen, lipids provide more than twice the energy of that of glucose or glycogen. Similarly, the energy storage capacity of lipids over 1000 times that of glucose and 50 times that of glycogen. Therefore, fat molecules (an example of lipids) contain more energy-containing bonds than simple sugars (e.g. glucose)
Answer:
B) Pure culture.
Explanation:
Obtaining a pure culture involves culturing the organism on the bacteriologic agar. Initially blood agar is used because it supports the growth of many bacteria and the type of hemolysis can be observed.
In order to obtain pure cultures, following steps are done :
1)The bacteria are normally streak onto solid media.
2) Inoculating loops are used for streaking.
3) Then the plate is incubated at desired temprature.
4) Then after sometimes , colonies are visible wherever <u>a microbial cell capable of growth on particular medium was deposited on the agar surface.</u>
As in the above scenario , a bit of isolated colony is taken and is inoculated in a separate medium thus a pure culture is formed.
Hence option B) Pure culture is the right answer.
Answer:
++
Explanation:
This is an example of ecological interaction where the actions of one organism is benefitting the other i.e. both organisms are benefitting from the relationship. This type of relationship is referred to as MUTUALISM.
In this example, the cellulose-digesting organism lives in the guts of the termite. The termite benefits from this association by getting its ingested cellulose (in form of wood) degraded or broken down. Termites feed on wood and naturally, they don't contain the enzymes that helps it digest it, hence, they depend on the enzyme secreted by these organisms in their guts to digest cellulose.
The cellulose-digesting organism gets shelter, protection and food in return as they cannot survive outside the termite's guts. Hence, it is a win-win (++) situation for the two organisms.
