QUESTION 1
In this case, the statement is true. This type of membrane is called membrane teichoic acids where the teichoic acid is non-covalently attached to the plasma membrane
QUESTION 2
The correct answer is Braun's lipoprotein. This lipoprotein is found at the cell wall and it is covalently attached to the peptidoglycan layer .

1. Placing a Gram positive bacterial cell in a hypotonic environment will most likely A. swell and lyse the cell. B. shrink and shrivel the cell. C. swell but not lyse the cell. D. have no effect on the cell 2. Mutations to which of the following structure(s) will cause harm to a Gram positive cell? (Choose all that apply) A. Lipoteichoic Acids/Teichoic Acids B. Plasmid C.

Which statement is TRUE? The membrane potential is negative on the cytoplasmic side and positive on the matrix side. The genomes of mitochondria don't range in size across species. The inner membrane is quite permeable because it contains mitochondrial porin, or VDAC (voltage-dependent anion channel). Mitochondria are semi-autonomous organelles, because mitochondria depend on the cell, and cells that contain mitochondria in turn depend on these organelles for oxidative phosphorylation. In bacteria, ATP-synthesizing complexes are located in the outer plasmatic membrane.
