Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
How do humans get glucose needed for cell respiration?
A
Inhale
B
Exhale
C
It naturally regenerates in our body
D
We eat it
Explanation: 

Detailed explanation-1: -Through the process of cellular respiration, the energy in food is changed into energy that can be used by the body’s cells. Initially, the sugars in the food you eat are digested into the simple sugar glucose, a monosaccharide. Recall that glucose is the sugar produced by the plant during photosynthesis.

Detailed explanation-2: -To start the process of cellular respiration, we need to get glucose into our cells. The first step is to eat a carbohydrate-rich food, made of glucose. Let’s say we eat a cookie. That cookie travels through our digestive system, where it is broken down and absorbed into the blood.

Detailed explanation-3: -When the stomach digests food, the carbohydrate (sugars and starches) in the food breaks down into another type of sugar, called glucose. The stomach and small intestines absorb the glucose and then release it into the bloodstream.
