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.

The correct answer is active transport. Active transport entails movement of substances against a concentration gradient and requires use of energy in form of ATP and use of protein pumps. Active transport is used to enhance several activities in the body such as movement of nutrients from the small intestines to the blood stream, this ensures that all the nutrients have moved from the lumen,
Answer:
There are many invasive animal sand plants which are harmful for native flora and fauna. Some of the invasive or alien species are as following:
<u>1. The Nile Perch:</u><em> </em>Nile Perch is a type of fish which is native to African lake and river systems but if it is introduced in other countries lake it can be dangerous to other fishes in that lake. It was earlier introduced to Lake Victoria but after sometime it was evaluated that native fishes got extinct and the Nile Perch become very huge in size.
<u>2. The cotton whitefly: </u> Cotton whitefly are native to India but now can be found on most of the continents and have very bad impact on the fauna or agricultural plants. They have capability of transmitting upto 100 different plant viruses. find them thriving
<u>3. The desert locust:</u> The desert locust is a species of locust which can fly and are one of the most disastrous migratory pests in the world. They feed over green green vegetation, including pasture, crops and fodder. They have very bad impact on native flora as they are migratory pests. They are found in Africa and migrated to nearby countries such as India and damages the native flora.
<u>4. European starlings:</u> European starlings are the bird species which fight with native species for food and shelter. They are found in Alaska and Mexico and proved invasive in U.S. as the number of native birds decreased with their introduction.
