Answer:
- In glycolysis, glucose is split into two pyruvate and makes some ATP
- The Krebs cycle produces ATP, NADH and CO2
- NADH gives electrons to the ETC
- As electrons move down the ETC, a H+ gradient is made
- H+ pass through the ATP synthase to make ATP
Explanation:
This question is describing the processes involved in cellular respiration. Cellular respiration is the way through which living cells synthesize energy (ATP) by breaking down sugar. Cellular respiration involves three major steps: glycolysis, Krebs cycle, and oxidative phosphorylation (electron transport chain).
- Glycolysis is the process whereby glucose is broken down into pyruvic acid or pyruvate with the synthesis of net 2 ATP molecules.
- Kreb's cycle produces ATP, NADH and CO2.
- NADH is an electron carrier that donates electrons to the Electron transport chain (ETC).
- Electrons move down the ETC to produce a proton (H+) gradient
- The proton (H+) passes through an enzyme called ATP synthase to make ATP from ADP molecule.
Answer:
In which phase of mitosis do chromosomes align at the center and spindle fibers become visible? Explanation: Mitosis involves four distinct stages: prophase, metaphase, anaphase, and telophase. Prophase is the first step of mitosis, during which chromosomes condense and the nuclear envelope dissolves.
the answer is B: so it isa line
The answer is Number 4. Gemetophyte

This is extremely vague, but assuming this is regarding concentration gradient in the nervous system, the Sodium-Potassium pump is responsible for transporting sodium and potassium.
