Yes we have to maintain homeostasis so our bodies have to adapt to Mother Nature
The Lock-and-key mechanism was first proposed by Emil Fischer which described as the enzymatic reactions whereby an enzyme with a single substrate binds temporarily to form a substrate complex.
The lock-and-key mechanism is usually associated with the complementary shapes of an enzyme with a single substrate, wherein the lock that is being referred to is the enzyme and the substrate is the key. One right sized substrate (key) fits into the active site (key hole) of the enzyme (lock).
The active site which is mentioned above is structurally complementary to the substrate. This is the temporary binding site on the enzymes. Just like a lock and key, the enzyme as the lock and the substrate as the key is said to fit together.
Answer:
Having a repetitive enzyme system would allow more than one enzyme to catalyze a particular reaction. If one of the types of enzyme is not able to perform its function due to temperature or any other factor, then another kind of enzyme would be able to catalyze the reaction. Hence, having repetitive enzyme systems is very effective in carrying out the metabolic functions of the body even when conditions are not favourable.
<u>Answer:</u>
Australia has invested in capital goods, so their standard of living and GDP increasing is true.
<u>Explanation:</u>
- Capital goods are goods or objects that is used to produce other good or objects. Examples are buildings, furniture etc.,
- GDP measures the economic activity of the country.
- Investing in these goods has led to the "average household net-adjusted disposable income per capita as USD 32,759 a year", this increased the standard of living and resulted Australia as 'one of the highest' in the world.
