Identify all correct statements1 Primary protein structure i
Identify all correct statements:1. Primary protein structure is stabilized by peptide bonds between a linear sequence of amino acids.
2. Secondary protein structure is stabilized by hydrogen bonds between R groups adjacent amino acids.
3. Both primary and tertiary protein structure may be stabilized by covalent bonds.
4. All proteins display primary, secondary, and tertiary levels of protein structure.
 5. Larger organisms do not generally have larger cells than smaller organisms; instead, they have more cells.
 6. Plants obtain ATP from aerobic respiration only in the dark.
 7. The endomembrane system includes the nuclear envelope, endoplasmic reticulum, Golgi apparatus, lysosomes, vacuoles, and the plasma membrane.
Identify each statement as CORRECT or INCORRECT. Change each incorrect statement to a correct one.
 1. The volume of an average eukaryotic cell is ten times the volume of an average prokaryotic cell.
2. Plant cells produce ATP during photosynthesis, whereas animal cells produce ATP
during aerobic respiration.
3. The nucleus, chloroplasts, and mitochondria within a eukaryotic cell are bounded
by double membranes.
Solution
1. Primary protein structure is stabilized by peptide bonds between a linear sequence of amino acids. ---> TRUE
2. Secondary protein structure is stabilized by hydrogen bonds between R groups adjacent amino acids. ---> FALSE (interactions between R groups occur in tertiary structure)
3. Both primary and tertiary protein structure may be stabilized by covalent bonds. ---> TRUE
4. All proteins display primary, secondary, and tertiary levels of protein structure. ---> TRUE
 5. Larger organisms do not generally have larger cells than smaller organisms; instead, they have more cells. ----> TRUE
 6. Plants obtain ATP from aerobic respiration only in the dark. ---. TRUE
 7. The endomembrane system includes the nuclear envelope, endoplasmic reticulum, Golgi apparatus, lysosomes, vacuoles, and the plasma membrane. ----> TRUE
