1Km is a term used to describe amount of bound to an enzyme

1)Km is a term used to describe amount of ___ bound to an enzyme?

a. Ligand

b. amino acid

c. neurotransmitter

2)Energy production is a highly correlated with the amount of _?

a. oxygen consumed

b. food consumed

c. energy used

3)V02max refers to an animals?

a. maximum oxygen consumption

b. maximum carbon dioxide usage

c. maximun oxygen usage

Solution

1)Km is the concentration of substrate (ligand) bound to an enzyme which allows it to achieve Vmax. As the concentration of substrate increases the enzymes gets saturated with ligand and achieves maximum rate of reaction called as Vmax.

So answer is Ligand.

2)Energy production is highly correlated to Oxygen consumption. Metabolism occurs in the body through burning food and amount of oxygen consumption and CO2 released shows the metabolism rate. The amount of energy produced by different types of food such as carbohydrates, proteins, and fats is directly proportional to the amount of oxygen consumption.

So, answer is Oxygen consumption

3)VO2max refers to maximum oxygen consumption during peak exersise.This is measured as Millilitre of oxygen consumed per per kg body weight per minute and represents the physical fitness of an individual. This is important in determining endurance capacity during prolonged high intensity exersise.

So, answer is a. maximum oxygen consumption
