Decreased pH in mitochondria
Increased ATP
Decreased pH in cytosol
Increased hydrolysis
Decreasing glycogen and triglycerides
Increased MAP kinase activity
Poor ion transport → For each one:→ What normally happens?→ What is wrong now?→ How does it mess up the cell?

- You have been hired as a public relations specialist to give invertebrates a good name. After all, they are much more than just creepy crawly bugs! Your first task though is to convince yourself that is true. The best way to do that is to start close to home. Find something in your house that is a product obtained directly from an invertebrate or only due to an invertebrate’s actions. Describe the product, its function and utility, as well as any human manufactured alternatives. Be sure to highlight the advantages of obtaining this directly from nature. Keep in mind, a product can be something you use, wear, eat, or enjoy for its visual appeal.arrow_forwardUse the following tree diagram to answer Questions #8-10. 8) Which of the following two animals are the most closely related based on the tree to the left? a) Pig and camel b) Hippo and pig c) Deer and cow 9) CIRCLE on the tree diagram where the common ancestor between a hippo and a cow is. 10) Put a SQUARE on the tree diagram where the common ancestor between a pig and a peccary is.arrow_forwardExplain: Healthy Cell Function Overview→ Briefly describe how a healthy cell usually works: metabolism (ATP production), pH balance, glycogen storage, ion transport, enzymes, etc. Gene Mutation and Genetics Part→ Focus on the autosomal recessive mutation and explain: How gene mutation affects the cell. How autosomal inheritance works. Compare the normal and mutated gene sequences simply. → Talk about possible consequences of a faulty hydrolytic enzyme.arrow_forward
