Question

which problem is most directly caused by the lack of protein in the patients diet?
a cells cannot make atp because carbohydrates are absent
b blood cannot transport nutrients because lipids are missing
c dna cannot store information because nucleic acids are missing
d muscles and hair are weak because structural proteins are missing

question 19 (1 point)
the patient has no fat intake. which consequence is the most likely result due to this problem?
a they cannot replicate dna properly
b they cannot store long - term energy or insulate organs
c they cannot form enzymes to speed up reactions
d they cannot carry oxygen in the bloodstream

question 20 (1 point)
eating only carbohydrates gave the patient quick bursts of energy followed by crashes. what property of carbohydrates explains this?
a they are broken down quickly into simple sugars like glucose
b they contain nitrogen, which provides stable energy
c they are stored in large fat droplets for long - term energy
d they fold into complex 3d shapes that release energy slowly

Explanation:

• For the first question, proteins are important for the structure of muscles and hair. Lack of structural proteins leads to weakness in these.
• For the second question, fats are used for long - term energy storage and insulating organs. Without fat intake, this function is impaired.
• For the third question, carbohydrates are broken down quickly into simple sugars like glucose, which causes quick energy bursts followed by crashes.

Answer:

• Question 18: d. Muscles and hair are weak because structural proteins are missing
• Question 19: b. They cannot store long - term energy or insulate organs
• Question 20: a. They are broken down quickly into simple sugars like glucose
