During G1 phase, the cell grows in size and synthesizes mRNA and protein that are required for DNA synthesis. Once the required proteins and growth are complete, the cell enters the next phase of the cell cycle, S phase. The duration of each phase, including the G1 phase, is different in many different types of cells.
to begin with in G1 segment, the cellular grows bodily and will increase the volume of each protein and organelles. In S phase, the mobile copies its DNA to supply two sister chromatids and replicates its nucleosomes. subsequently, G2 section entails similarly cellular boom and business enterprise of cellular contents.
G1 - segment is likewise called anaphase, as in the course of this section the cellular shops ATP for cellular department.
The G1 phase is frequently referred to as the increase phase, due to the fact this is the time in which a cell grows. in the course of this phase, the cellular synthesizes diverse enzymes and vitamins which can be wished later on for DNA replication and cellular department.
G1 section collectively with the S phase and G2 section comprise the long increase period of the cell cycle cell department referred to as interphase that takes region before cellular department in mitosis (M phase). all through G1 segment, the cellular grows in size and synthesizes mRNA and protein which are required for DNA synthesis.
In G1, cells accomplish most in their growth; they get larger in size and make proteins and organelles wanted for regular functions of DNA synthesis. here, proteins and RNAs are synthesized, and, extra in particular the centromere and the alternative components of the centrosomes are made.

Answer:
At the beginning, aerobic respiration is used by his legs to generate energy when there was still sufficient oxygen intake for energy to be generated via oxidative phosphorylation.
Towards the end of the ride, his legs are generating energy through anaerobic respiration due to insufficient oxygen intake to keep up with the energy requirement of his muscles as he cycles continuously. Through anaerobic respiration, pyruvate from glycolysis is converted to lactate by lactate dehydrogenase instead of being channelled to the mitochondria for oxidative phosphorylation. The accumulation of lactate in his muscles is what causes the pain in his leg. After he stops the activity, the pain would reduce as lactate is transported to the liver to be reconverted back into pyruvate.
The digestive tract overlaps in many layers (It can even reach microsocpic overlaping) allowing it to fit inside a person's body.
