greater surface area for ATP production
What does the folding of the mitochondrial inner membrane provide? greater ability to allow for osmosis increased surface area for photosynthesis increased space for protein synthesis greater surface area for ATP production greater ability to remove waste from the cell cytosol
plasma membrane
What must materials pass through to enter or leave a cell? lysosome vacuole plasma membrane ribosome nucleus
smooth endoplasmic reticulum - storage of water
Which of the following is an incorrect match? ribosomes - protein synthesis mitochondria - production of cellular ATP smooth endoplasmic reticulum - storage of water lysosomes - cellular digestion Golgi apparatus - protein alteration and packaging
ribosomes
Which of the following organelles is not surrounded by a membrane? ribosomes mitochondrion chloroplast lysosomes nucleus
It converts light energy into chemical energy.
Which of the following statements describes the function of a chloroplast? It stores water. It manufactures proteins. It converts light energy into chemical energy. It converts chemical energy into heat energy. It aids in intracellular digestion.
mitochondria
Which organelle is required for producing ATP for cellular work? chloroplast Golgi apparatus nucleus vacuole mitochondria
bind to signal proteins from other parts of the body.
Without receptor proteins, a cell would not be able to bind to signal proteins from other parts of the body. perform metabolic reactions. transport water into the cytoplasm. divide. allow the passage of H ions into the cell.
fluids may leak out past the barrier the junction would create.
Without tight junctions in certain tissues, cells would not be able to migrate during their development. the tissues would not be able to expand and stretch without damage. nutrients would not be able to be passed from cell to cell. cells would not be able to communicate with each other. fluids may leak out past the barrier the junction would create.
