Answer: Stratum Corneum

Epidermis. The epidermis is the thin outer layer of the skin. It consists of 3 types of cells: Squamous cells. The outermost layer is continuously shed is called the stratum corneum

Explanation:

stratum corneum

The epidermis has no blood supply and depends on diffusion from the dermal cells for its metabolic needs. The dead-cell layer of the stratum corneum provides the protection from water loss that allows vertebrates to dwell on land

Which of the following is correct? Which of the following is correct? Most of the ATP are produced by substrate-level phosphoryl
Nezavi [6.7K]

Answer:

Each FADH2 yields about 1.5 ATP via oxidative phosphorylation.

Explanation:

Most of the ATP molecules are produced by oxidative phosphorylation, not by substrate-level phosphorylation. During glycolysis, 2 ATP molecules per glucose are produced by substrate-level phosphorylation. Similarly, Kreb's cycle also yields 2 ATP per glucose by substrate-level phosphorylation.

For each pair of electrons transferred to O2 from FADH2 via electron transport chain, 4 and 2 protons are pumped from matrix towards the intermembrane space by complex III and complex IV respectively. It generates the proton concentration gradient required to drive the synthesis of 1.5 ATP molecules. Since oxidation of FADH2 is coupled to the phosphorylation of ADP to form ATP, the process is called oxidative phosphorylation.

When the protein gramicidin is integrated into a membrane, an H+ channel forms and the membrane becomes very permeable to proton
Naddika [18.5K]

Answer:

The electron transport chain may be defined as the sequential steps of the oxidation and reduction of the cytochromes. The electron transport chain is important for the production of ATP.

The gramicidn protein is an ionophoric antibiotic that can affect the electron transport system. The electron transport rate, oxygen uptake and proton pumping remains the same as more hydrogen ions will enter in the cell.  But the ATP synthesis rate might decrease and completely stop by using gramicidin.

Which of the following is not a piece of molecular evidence supporting the endosymbiotic theory? .A. Some organelles divide by f
ElenaW [278]
The best answer is B. The endosymbiotic theory states that mitochondria and chloroplasts have striking similarities to bacterial cells: 1. they have their own DNA, which is separate from the DNA found in the nucleus of the cell. 2. Both organelles use their DNA for to produce many proteins and enzymes required for function. 3. They are both surrounded by a double membrane. 4. They reproduce just the way bacteria do, replicating their own DNA and directing their own division.
