8 paź 2023 · The four main steps of aerobic respiration are glycolysis, pyruvate decarboxylation (link reaction), the Krebs cycle (Citric Acid Cycle or Tricarboxylic Acid Cycle), and the electron transport chain with oxidative phosphorylation.
ATP, the charged battery, has energy that can be used to power cellular reactions. Once the energy has been used up, the uncharged battery (ADP) must be recharged before it can again be used as a power source. The ATP regeneration reaction is just the reverse of the hydrolysis reaction:
Labelled diagram is an open-ended template. It does not generate scores for a leaderboard.
12 sie 2020 · Cellular respiration occurs in three stages. The flow chart in the figure shows the order in which the stages occur and how much ATP forms in each stage. The names of the stages are glycolysis, the Krebs cycle, and electron transport. Each stage is described below. Glycolysis is the first stage of cellular respiration.
Students describe each stage of the cell cycle (S and G2 phases shown) using the picture of the cell at that stage. Students will also summarize the stages of the cell cycle in a diagram. There is a link for them to research the G0 phase, which some cells enter.
Essentially, the energy released from the ATP hydrolysis provides the energy required to power the pump and transport Na + and K + ions. ATP performs cellular work using this basic form of energy coupling through phosphorylation. The sodium-potassium pump is an example of ATP powering cellular work.
ATP (adenosine triphosphate) is the energy-carrying molecule used in cells because it can release energy very quickly. Energy is released from ATP when the end phosphate is removed.
