I found the full exercise on the internet. Attached is an image of the characteristics and the types of muscle fibres.

Fast twitch:
- few mitochondria (most of the energy comes from acid lactic fermentation)
- low myoglobin content (O2 is not used as the main source of energy)
- shorter twitches
- anaerobic (uses mainly glucose and no O2)
- easily fatigued (as soon as glucose storage finishes fatigue comes in)
- high glycogen content (glucose as the main source of energy and therefore more glucose storage in the form of glycogen)

Slow twitch:
- high myoglobin content (energy comes from O2 and therefore is needed much myoglobin)
- aerobic (uses O2)
- low glycogen content (as O2 is the main source of energy, glucose is not needed as much)
-longer twitches

Which of the statements regarding the cell cycle is true? Group of answer choices It is regulated by cyclins and CDKs. Different
MA_775_DIABLO [31]

Answer:

All of these choices are correct.

Explanation:

Cell cycle is the process of growth and division of cell. It comprises of interphase and mitosis. In interphase the cell grows, replicates its genomic content and prepares itself for division. In mitosis the division occurs.

Cell cycle is controlled by a group of kinases called as Cyclin dependent Kinases (CDKs). They act by phosphorylating their substrates. They are of various types like Cdk1, Cdk2, Cdk4 etc. They become active when they bind to a regulatory protein called cyclin. They are also of various types like Cyclin A, Cyclin B, Cyclin C etc. Level of cyclin and corresponding CDK increases and decreases according to the stage of cell cycle. For example in S phase of cell cycle concentration of cyclin A and E shoots up. CDK2 is able to bind to these cyclin molecules and hence it becomes active.

Cell cycle has major checkpoints where the condition of cell is analysed before it proceeds to the next stage of cycle. If any abnormality is detected, repair mechanism is activated or the cell is killed. Checkpoints do not allow cell cycle to proceed in damaged cells.

p53 is a tumor suppressor protein which can halt cell cycle when it detects some abnormality in cell. It usually acts in G1/S checkpoint (before the DNA replication starts in cell) and G2/M checkpoint (before the cell division begins). Hence, all of the above statements are true.
