Answer:
Electron transport chain
Explanation:
In all eukaryotes electron transport chain is located in the inner mitochondrial membrane where it serves as the site of oxidative phosphorylation (production of ATP) through the action of ATP synthase.
Electron transport chain consists of protein complexes that transfer electrons from donors to acceptors via redox reactions. As a result of electron transport, protons (H+ ions) are pumped across a membrane and electrochemical proton gradient is formed. Proton gradiend is used for the ATP synthesis.
Answer:
Active transport:
- Diffusion (one to far left)
- Facilitated diffusion (the one with glucose)
- Osmosis (the one with water)
Passive transport:
- Protein pump (one to far right)
Answer:
A
Explanation:
They are examples of endocytosis because they all engulf or bring in substance into cell
In order to cope in times where normalcy is not present, methods such as social distancing, masks, and sanitation are incredibly important.
