Answer;
Quaternary structure
Explanation;
-Amino acids link together end-to-end forming the primary structure of proteins.
-Chemical properties of amino acid groups within a sequence interact with one another in secondary protein structure resulting in hydrogen bonding and chain folding.
-Intramolecular bonding of polypeptide chains produces numerous alpha helices and beta sheets.
-Globular and fibrous shapes are created with tertiary structure of proteins caused by further folding due to disulfide bridges, hydrophobicity and Van der Waals forces.
-More than one globular or fibrous protein subunit now interact to produce quaternary structure, which results from ionic, hydrophilic, and hydrophobic interactions.
Answer:
To transport water and nutrients up the plant stem.
Explanation:
I need more information to answer this question.
The sugar that is produced in photosynthesis is a glucose.
- Glucose can be used to provide energy for cellular activity.
- Excess of glucose is transformed into starch. Starch is transported into storage organs.
- Glucose can be transformed into cellulose, pectin, and chitin. These molecules are structural materials for the cell walls.
- Fats and amino acids can be formed from glucose. These molecules can serve as structural materials or can be stored.
The answer is A, a glucose molecule is gradually broken down into carbon dioxide and water. i hope this helps
