The energy release from sequential redox reactions provides energy to cells most directly by Using that energy to pump protons.
- By transferring electrons during chemical reactions, catabolic pathways break down organic molecules, generating energy that is then used to produce ATP.
- In an oxidation-reduction (redox) reaction, the process of losing electrons (making a chemical more positive) is referred to as oxidation, while the process of gaining electrons (making a substance more negative) is referred to as reduction.
- The inner mitochondrial membrane's electron transport chain receives electrons from NADH and FADH2, which causes an H+ accumulation in the inner membrane space.
- The direct energy source for ATP synthesis is this proton gradient (gradient of H+) flowing via the membrane enzyme complex ATP synthetase.

Spindle fibers extend from the poles and overlap at the spindle equator where some attach to chromosomes to help separate them during cell division.
<h3>What is spindle fiber?</h3>
A single filament that travels from the poles to the center is a spindle fiber. Aster is a single filament as well, but the aster differs in its placement.
<h3>What is spindle equator?</h3>
Chromosome alignment at the spindle equator improves the efficiency of bi-orientation. Chromosome congression, a procedure that moves chromosomes from close to spindle poles to the equator, is necessary for this alignment to take place.
<h3>What is spindle in cell?</h3>
A protein structure called a spindle fiber divides a cell's genetic material.

A unicellular organism lacking a membrane bound nucleus , mitochondria
Answer:
A single glucose molecule produces about 38 molecules of ATP through the process of cellular respiration.
Explanation:
Cellular respiration is a metabolic pathway that breaks down glucose and produces ATP.
I hope this helps. :)
