aleksklad [387]3 years ago
5 0
Formation of the Earth's Atmosphere. The early Earth was very different from our Earth today. The early Earth experienced frequent impacts from asteroids and meteorites and had much more frequent volcanic eruptions. There was no life on Earth for the first billion years because the atmosphere was not suitable for life.

NAD+ is a limiting factor in glycolysis. In the absence of ____________________ the conversion of (1) ____________________ to NA
scoray [572]

The correct options to fill in the gaps are:

  • ADP; NADH, and electron transport chain
  • alcohol fermentation; lactic acid fermentation; acetaldehyde; NADH; and NAD+

<h3>What is the role of NAD+ in glycolysis?</h3>

NAD+ serves as an electron acceptor in glycolysis. It accepts two electrons to become reduced to NADH + H+.

NAD+ is a limiting factor in glycolysis. In the absence of ADP, the conversion of NADH to NAD+ via the electron transport chain is prevented from happening.

In eukaryotes, the hydrogen atoms of the molecules mentioned in are transferred to certain organic molecules in one of two methods: alcohol fermentation as can occur in yeast and lactic acid fermentation as can occur in human cells. In the process mentioned in, the hydrogen atoms are passed to acetaldehyde, which is then converted to a molecule of ethanol. During this a molecule of NADH is oxidized to a molecule of NAD+, which allows glycolysis to continue on.

In conclusion, NAD+ concentration is limiting to glycolysis.

Slightly acidic rainwater can contribute to which process
ycow [4]
Acid rain can cause many problems, such as stripping paint and burning skin, but I believe the answer you are looking for is "decay," which is the process that occurs when an organism decomposes.
