In eukaryotic cells, glycolysis and fermentation reactions occur in the cytoplasm. The remaining pathways, starting with pyruvate oxidation, occur in the mitochondria. Most eukaryotic mitochondria can use only oxygen as the terminal electron acceptor for respiration.
Answer:
Theories have been confirmed through tests; hypotheses have not been tested.
Explanation:
Theories have to be proven, whilst hypotheses is an experiment that is carried out without yet knowing the outcome.
The most important differences between a transmission electron microscope and a scanning electron microscope are: Rather than the broad static beam used in TEM, the SEM beam is focused to a fine point and scans line by line over the sample surface in a rectangular raster pattern

The correct answer is - Its electrons are used to form NADPH.
On receiving light energy, electrons are expelled from the reaction center of photosystem II. The expelled electrons finally reduces oxidized NADH⁺ to NADH. The oxidized reaction center of photosystem II split water into protons, electrons and oxygen. The electrons released from water reduces oxidized reaction center of photosystem II. Thus, oxidized reaction center of photosystem II gets back its expelled electrons. Therefore, electrons from water forms NADH.
Proteasomes are a large protein complex present in all eukaryotic cells that break down protein.
<h3>What are proteasomes?</h3>
It is considered one of the main pathways involved in the processes of enzymatic protein degradation.
It is the group of proteins that are associated forming large complexes, whose function is to digest cytoplasmic proteins, generating peptides.
Therefore, we can conclude that proteasomes is a large protein complex present in all eukaryotic cells that breaks down protein .
