Question

question 1 (mandatory) (3 points)
organic molecules are often referred to as the \molecules of life.\ watch the video below about organic molecules and identify each one by matching it to its function.
biological molecules | cells | biology...
proteins

1. responsible for producing different kinds of sugar molecules
2. enzymes during photosynthesis, antibodies for fighting infection
3. stored as fat, vitamins a&d

lipids
carbohydrates
question 2 (mandatory) (2 points)
a ____ is an organic molecule that consists of c, h, o atoms in a ratio of 1:2:1.
a) carbohydrate
b) protein

Explanation:

Step1: Recall protein function

Proteins can act as enzymes in biological reactions like photosynthesis and also function as antibodies to fight infections. So Proteins match with 2.

Step2: Recall lipid function

Lipids can be stored as fat in the body and also include fat - soluble vitamins like A and D. So Lipids match with 3.

Step3: Recall carbohydrate function

Carbohydrates are involved in the production of different sugar molecules. So Carbohydrates match with 1.
For Question 2:
Carbohydrates are organic molecules with C, H, O atoms in a 1:2:1 ratio.

Answer:

Question 1:
Proteins - 2
Lipids - 3
Carbohydrates - 1
Question 2: a) carbohydrate
