The average 70 kg (150 lb) being has 5.5 L of blood (1.05 g/mL). How many 1 oz drinks of 20% alcohol by volume (40 proof) must b
AlekseyPX

Answer:

The total blood given is 5.5 liters

Thus, total alcohol needed for BAC (blood alcohol content) to exceed 0.1 gram per 100 ml will be 0.1/100 × 5500 = 5.5 grams alcohol.

1 oz = 28.3 grams

28.3 gram water = 28.3 ml

It has 20 percent alcohol by volume,

Therefore, alcohol in one drink will be:

20/100 × 28.3

= 5.66 ml

= 5.66 × 0.79 (density of ethanol)

= 4.47 gram

Thus, no of drinks will be 5.5 g / 4.47 g = 1.2

Hence, 1.2 drinks will make the BAC to exceed 0.1 g / 100 ml in the blood.

Carbohydrates are the primary source of energy for the human body. If your body lacks enzymes that break down carbohydrates, it

Ambitious

If your body lacks enzymes that break down

carbohydrates, it would be unable to get sugar molecules for energy production.

If you lacked the enzyme to digest proteins, you may not absorb enough amino

acids.

The digestive system in our body changes

carbohydrates into glucose; also known as blood sugar to be use as an important

source of energy. Meanwhile, amino acids are organic compounds that combine to

form proteins, which are the building blocks of life.

In the presence of DCPIP which statements would be true? (for this and other questions, assume there is an inexhaustible supply
Margarita [4]

Answer:

<u>The correct statements are A and D</u>

A.The photo-system will still continue to split water because it is still losing electrons

D.The ATP yield would be unaffected

Explanation:

DCPIP is a redox-sensitive dye, not an electron transport chain blocker, and hence, imparts change in the wavelength when electrons are transferred. This allows rest of the steps of photo-system to be carried on normally, including splitting of water to generate oxygen as well as generation of ATP.
