Answer:this is definitely a covalent bond
:)
Answer:
The correct answer is D
Explanation:
The primary function of the large central vacuole in a plant cell is to maintain turgor pressure against the cell wall of the plant. This vacuole also perform other functions such as storage (water and other nutrients) and waste disposal. When this vacuole is damaged in plant cells, the cells may no longer be able maintain turgor pressure and store materials (water inclusive). Also, <u>If the cell cannot store raw materials via the large central vacuole, the chloroplast will lack the raw materials required for photosynthesis</u>.
Answer:
Because enzymes have many functions as chemical catalysts in numerous chemical reactions (for example in metabolism). By lowering the activation energy, they make it much easier to carry out reactions. They are also indispensable for signal transduction and cell regulation, often via kinases and phosphatases. They also generate movement, with myosin hydrolyzing ATP to generate muscle contraction, and also transport cargo around the cell as part of the cytoskeleton. Other ATPases in the cell membrane are ion pumps involved in active transport.
