Which of the following accurately describes fermentation? A. All types of fermentation produce carbon dioxide. B. Fermentation c
an only occur in the presence of oxygen. C. Fermentation makes NAD+ needed to keep glycolysis going. D. Fermentation generates more ATP than cellular respiration.
The correct answer is C. Fermentation makes NAD+ needed to keep glycolysis going. The other options are inaccruate since: for A: there are types of fermentation that does not produce carbon dioxide like Lactic acid fermentation for B: many types of fermentation only occurs in the absence of oxygen (anaerobic process) for B: respiration produces around 36 ATP while fermentation only generates around 2 ATP
In active transport, materials move from an area of high concentration to an area of lower concentration (goes down the concentration gradient) and it requires or uses energy in the form of ATP (adenosine triphosphate)
Apoptosis also plays a key role in human development. For instance, as we saw in the introduction, your hand started out as a paddle-like block of tissue when you were an embryo. The block was “carved” into fingers by apoptosis of the cells in between the developing fingers.
