which transcription factor binds directly to the tata-box sequence?

Answers

The transcription factor that binds directly to the tata-box sequence is TFIID. This transcription factor (TFIID) is a macromolecular protein complex.

The TATA box is a fundamental nucleotide gene sequence that forms the eukaryotic core promoters, which are required to initiate transcription.

TFIID is a macromolecular protein complex (also called the RNA polymerase II preinitiation complex), which acts as a general transcription factor during the initiation of eukaryotic transcription.

TFIID recognizes and binds to the TATA box (core promoter) and also binds with different activator and repressor proteins in order to regulate the transcriptional activity.

One of the hottest ideas in engineering today is the concept of building an energy capturing system
similar to photosynthesis. The system would use light energy to make artificial food. What two
parts would such a system need, and how must these parts interact if they are to be like
photosynthesis?

Answers

The capturing device and converter are the two parts needed by the energy capturing system in order to make food.

If an energy capturing system wants to perform the same function of photosynthesis, then it must have two parts i.e. converter and capturing device. The capturing device works to capture or absorb light energy and send it to the place where this energy energy is converted into food.

The second part is the converted which convert light energy into food particles. These two parts interact with each other then the desire product will e achieved otherwise not so we can conclude that capturing device and converter are the two parts needed by the energy capturing system in order to make food.

When muscle tissue is exercising under anaerobic conditions, the production of ______ is important because it ensures a continuous supply of NAD

Answers

Given what we know about the biological mechanisms behind anaerobic exercise, we can confirm that the production of lactate ensures a continuous supply of NAD.

In order for us to undergo any physical exercise, it is imperative that we are able to produce energy within our cells. The energy used by cells is in the form of a molecule by the name of ATP, which is produced primarily through a process known as Glycolysis.

This is relevant given that in order for glycolysis to happen, a key protein is required known as NAD+. Lactate is produced from pyruvate only under anaerobic conditions because these are conditions that lack oxygen which is the only other source of NAD+, therefore, pyruvate must be converted to lactic acid to make it possible to continue glycolysis and the production of ATP.
