By moving substances across membranes, transport proteins make everything from nerve impulses to cellular metabolism possible. Without transport proteins, for example, the sodium-potassium gradient that allows our nerves to fire would not exist.
So the original weight is 175 pounds, and the after weight is 161 pounds. so you can subtract 175 by 161, and then divide it by 175 pounds. finally times it by 100, you will get 8%
Nucleus - regulates all cell activity, and also holds the DNA
Smooth endoplasmic reticulum - lipid and carbohydrate synthesis.
Rough er - produces and modifies proteins
Located next to the nucleus
Golgi apparatus - <span>modify, sort, and package macromolecules for cell secretion </span>
Ribosome - <span> assembles the twenty specific amino acid molecules to form the particular protein molecule</span>
Mitochondria - converts energy into compounds that are easier for the cell to use
Chloroplast -<span> captures the energy from sunlight and converts it into food that contains chemical energy in a process called photosynthesis</span>
Lysosomes - breaks down, recycles macromolecules (lipids, carbohydrates, and proteins)
Perioxisome - where hydrogen peroxide and other harmful molecules are broken down by enzymes
Plasma membrane - controls the kinds and amounts of substances moving into and out of the cell; helps maintain cytoplasmic volume and composition
Cytoskeleton - structurally supports, impacts shape and moves cell and its componants
Centrioles - two perpendicular cylinders that form mitotic spindle fibers and microtubules for cilia and flagella, helps organize cell division
Cytoplasm - holds all organelles in place
Vacuole - stores water, salts, protein, and carbohydrates
Vesicles - <span>contains substances that recently entered the cell. Stores and transports newly synthesized molecules.</span>
Cell wall - supports and protects the cell, rigid barrier
