(-2,2) (-4,4) (-4,2) Reflecting across the y-axis changes positive X coordinates to negative and vice versa.
The answer is option (d). Enzymes act as biocatalysts that can accelerate biochemical reactions within the body. Their functioning is optimal at specific pH and temperature conditions. Excessive heat or cold treatment can impair enzyme activity, with cold decreasing activity due to reduced molecular movement.
Answer:
2. ER protein
4. insulin
6. lysosomal enzyme
Explanation:
Ribosomes serve as the cellular organelles responsible for synthesizing proteins since they create the necessary environment and machinery for this process.
Ribosomes can exist freely within the cytosol or be attached to the endoplasmic reticulum.
The proteins formed by free ribosomes are typically used within that same cell, such as DNA polymerase and ribosomal proteins, whereas proteins made by attached ribosomes are intended for transport throughout the cell, including insulin and lysosomal proteins.
Consequently, 2, 4, and 6 are correct.
Examples of biological macromolecules that depend on hydrogen bonding include proteins, nucleic acids, and polysaccharides. Hydrogen bonding plays a crucial role in numerous chemical processes and helps define the three-dimensional structure of folded proteins, which consist of enzymes and antibodies.
The potato does not increase in size because it is only a segment of the plant. Water absorbed from the soil is taken up by the roots and transported to other parts like leaves, but the potato itself does not directly absorb water from the soil.
