Answer:
D
Explanation:
the movement of your digestive system is through muscles within your wall that contract to push food down.
Answer:
Electron transport chain and ATP synthase
Explanation:
The inner mitochondrial membrane contains an electron transport chain and ATP synthesis. Four membrane protein complexes serve as the electron carriers and are embedded in the inner mitochondrial membrane. These protein complexes are called complex I, II, III and IV. Transfer of electrons from NADH and FADH2 to terminal electron acceptor oxygen occurs via these protein complexes.
During electron transfer, the pumping of protons towards the inner mitochondrial membrane creates an electrochemical gradient. The downhill transfer of protons back to the matrix via proton channel of ATP synthase drives phosphorylation of ADP. Therefore, presence of all the protein complexes of the electron transport chain and ATP synthase is required for electron transfer and ATP synthesis.
Answer:
You're a mitochondrion!
Explanation:
Don't you read your memes? The mitochondria is the powerhouse of the cell. It's known for synthesizing ATP, which is the body's energy currency! Without mitochondria, we would cease to exist real fast!
